1. Operation overview and general introduction

1.1. The control unit

The control looks as follows:

The precise appearance of your control may differ. 

Operation of the control is mainly done over the touchscreen. 

A description of the functions  and available touch controls is given in the next sections of this manual, aside of the  description of the specific functions.

1.2. Front control elements

The Start and Stop button, integrated in the touch screen user interface:

1.3. USB connectors

1.4. Operation and programming modes

The control's main screen looks as follows:

Depending on the navigation button which is active, the screen will differ. 

The above main  screen will appear having the Products function active. 

Just by tapping the various modes, the specific mode will be selected. 

The structure of the main screen is as follows: 

Title panel In the top the title panel is always shown. 

In this area you can find logo information, which  product is loaded and (when activated) the service row. 

Also machine indicators can be found  here.

Information panel In the information 

panel all functions and visualisation related to the selected modus are  displayed and can be found.

Command panel 

The command panel is part of the Information panel and is the location where the controls  related to the Information panel can be found.

Navigation panel 

The Navigation panel is the area where all the major modes can be found. This area is always  visible. 

The controls, large buttons with icons, can be used to directly switch from one mode to  the other.

1.5. Getting started

1.5.1. Introduction

In order to obtain a bend program for a product, the control offers the possibility to create a  program bend by bend 

and adjust specific parameters for each bend independently. This is done with the following steps:

1 Go to the Products mode in the navigation panel and start a new program by tapping New Program. 

2 Enter the program’s basic properties and continue by pressing Accept. 

3 Automatically the next menu is switched to, Tool-setup, to select the desired tooling. Check the tooling, modify upon desire and one can continue to the Program  menu.

4 In the Program menu one can start programming the bend specific parameters for  the first bend. To add the next bendstep to the program the function Add bend can  be used. This cycle can be repeated upon choice. 

5 Tap Auto and press the Start button in order to produce the programmed product.

1.5.2. Preparations

Before product programming can be started, the following preparations must be made. 

• The correct material properties must have been programmed in the Materials library.  You can find this on the Materials page in the Settings mode. 

• The correct tools must be programmed in the Tool Library. Tools are necessary to  create a CNC program. 

You can find the libraries for the different types of tools in the  Machine mode.

1.5.3. Modifying a program

The Program menu gives access to the numerical program and values of the active product. 

Existing programs can be modified via this menu. The independent bendsteps can be  selected and the programmed values can be monitored and modified if required. 

Axes positions, if applicable, are calculated according to the machine configuration.

1.5.4. The Auto menu and Manual menu, production modes

A product program can be executed via the Auto mode. In Automatic mode, 

a complete  program can be executed bend after bend. In the Auto mode the Step mode can be selected  to have each bend started separately.

The Manual mode of the control is an independent production mode. In this mode, one bend  can be programmed and executed.

 It is typically used to test the behaviour of the bend  system. More information about this can be found in chapters 5 and 6.

1.5.5. Back-up data, external storage Both product and tool files can be stored externally. 

These files can be stored on a USB stick.  This facilitates a back-up of important data and the possibility to exchange files between  Delem controls. 

More information about this can be found in chapter 7.

1.6. Programming aids

1.6.1. Listbox functionality

Several parameters on the control have a limited number of possible values. 

When selecting  such a parameter, by tapping the parameter line on the screen, 

the list of options will open up  near the position where you tapped the line, and the desired value can be selected.

To undo the selection and the opened listbox, tapping outside the box will make it close  without changing the selected parameter.

1.6.2. Parameter zoom functionality

To improve the focus on parameters, and to ease the use while programming,

 the parameter  zoom function will enlarge specific parameterlines when being programmed. When selecting  eg. 

force in Program mode, the force lines will expand giving them better focus while fine  tuning.

When selecting any other parameterline, the previous selection will be reduced and zoomed  out again, 

as the newly selected parameterline will be zoomed in at.

1.6.3. Navigation

Within some modes, the program screens are divided into tabs.

The tabs can easily be selected by just tapping them. When a tab is not completely visible or  not visible at all,

 just by dragging the tab row horizontally, the desired tab can be "pulled" in  sight and be selected.

1.6.4. Text input and editing

The cursor can be used to enter a specific value or text within an existing input. Just tap at the  desired position to do so. 

The cursor will appear and input will be added there.

1.6.5. Typing alphanumeric characters vs. special characters

Both alphanumeric characters and special characters can be used throughout the control. 

A  full on-screen alphanumerical keyboard will pop up when required. When editing a field which is pure numeric, 

the alphanumeric characters will be hidden. For  fields which enable to use alphanumerical strings, the keyboard is completely available. 

Special characters as ? % - can be found using the special character button on the left-lower  side of the keyboard.

Special characters (like á, à, â, ã, ä, å, æ) are supported by the on screen keyboard by  keeping a character (like ‘a’) pressed.

1.6.6. Messages centre

When messages are displayed coming from PLC, Safety systems or the Sequencer, these  messages can be ‘send’ to the 'Messages centre'. 

When a message is displayed  simultaneously the message centre symbol is shown in the top row of the page header, 

next  to eg. the keylock symbol. When tapping this message centre symbol the messages are taken  from the screen, giving way for normal programming and editing.

When tapping again the  actual messages are shown. When messages are in the background, 

the message centre symbol has an extra indicator to  show new incoming messages which are not yet shown.

1.6.7. Keylock function

To prevent for changes to products or programs, the keylock function offers the possibility to  lock the control.

There are two levels of locking the control. Program Lock and Machine Lock. 

• In Program Lock, only a product can be selected and executed in Automatic mode. 

• In Machine Lock, the machine is locked and the control can not be used.

To lock a control just tap the lock symbol in the top of the screen. Depending on the code  which is used, 

the control will be in Program Lock or Machine Lock. Program Lock wil show a  closed lock in grey. Machine lock will show the same lock but colored (red).

Lock symbols when Program Lock is active will also appear behind parameters to show the  lock is active and modification is not possible.

To unlock the control, tap the lock symbol and enter the appropriate code. 

After entering, the  lock symbol will show it is unlocked and the lock symbols behind parameters will disappear.

Codes can be changed upon desire. The procedure to manages codes can be found in the  Installation manual.

1.6.8. Manual positioning

On the manual positioning page in Manual mode and Automatic mode a slider at the bottom of  the screen can be used to position the axis. 

The distance moved with the slider determines  the speed of the axis. When the slider is released, the axis stops. 

The buttons at each end of  the slider can be used to fine-tune the axis position. When "sliding" the beeper gives feedback  that the axis is moving.

1.6.9. Software versions

The version of the software in your control is displayed at the System Information tab in the  Machine menu.

Example of version number:

V 1.2.3 

V stands for version 

V 1.x.x is the major version number 

V x.2.x is the minor version number 

V x.x.3 is the update version number

The major version number is increased when new major features are added to the software. 

These software changes require additional introduction and could change the normal working  order. 

The minor version number is increased when new features and enhancements are  integrated which do not change the working order.

 The update version number solely is used  for software changes when corrections are needed in the existing software version.

2. Products, the product library

2.1. Introduction

2.1.1. The main view

In Products mode an overview is given of the program library on the control. 

In this mode a  product program can be selected (loaded). After that a program can be modified or executed. 

Each item in the list consists of its Product ID, the Product Description, the Number of bends  in the product and the Date it was last used or modified.

If a product program is already active its ID is shown in the top of the screen. 

A program can  be loaded by tapping the product ID or any other part of the product's line.

When there are more products than can be visualised in the screen simply drag the list in the  upward direction until the product is visible. 

From then again a single tap on the product  selects the product and activates it in the control.

2.1.2. Product selection

To select a product a single tap will do. The product will be selected and loaded into the  memory.

From here production can be started by tapping Auto. Also navigation can start  through the Tool Setup and the numerical Program.

2.1.3. New Program, starting a numerical program 

To start a new numerical program tap New Program. After New Program is chosen,

the programming starts with its general details like e.g. Product  ID, Thickness and Material.

2.1.4. Edit, Copying and Deleting a product or program 

To delete a product in the Products mode select a product by tapping it. It will be selected. 

After that tap Edit and use Delete. To finally delete it confirm the question. To delete all  programs at once, tap Delete All.

To copy a product select a program and tap Edit and use Copy. After this the name of the  product can be programmed 

and the copy will be done. The copied product will be an exact  copy including tool setup.

2.1.5. Product Rename 

Products can also be renamed.This can be done in one single step: Rename allows the user  to give it a new name. 

To rename a product select a program and tap Edit and choose Rename from the list. For  Rename a new name can be given.

3. Tool configuration

3.1. Introduction

3.2. Standard procedure

When the function Tool Setup has been activated, the screen shows the active machine setup.

Both punch and die can be selected from the tool library.

The Upper and Lower tool, resp. Punch and Die, in the machine are shown and can be  changed.

3.3. Tool selection

When selecting tools, both upper and lower tool (resp. punch and die) can be selected from  the tool library. 

Tap Select Punch or Select Die to change tools to the configuration.

4. Product programming

4.1. Introduction

To edit an existing CNC program, select a product in the Products overview and select the  navigation button Program.

 When starting a new program, select New Program and after  giving in the main product properties and tool setup, 

the system will automatically switch to  Program.

In both cases, a screen as shown above should appear. Programming and changing data is  done in the same way in both cases.

The main screen shows the existing numerical program or, when starting a new program, the  first to be programmed bend. 

The bend selector in the top of the screen can be used to  navigate thru the bends. The indicated bends can be tapped to easily select the desired bend  data.

At the side of the main screen views and functions are indicated with command buttons

4.2. Program mode, parameter explanation

The main screen shows the available bends and from this main screen, from every available  bend, specific paremeters can be viewed and edited.

The product ID and product description are displayed in the top row on the screen.

4.2.1. Bend parameters

Method

Select the required bending method. The control supports the following standard  methods:

• air bend 

• bottoming 

• hemming 

• hemming & bottoming

Note 1 

The hemming bends are shown here with a special hemming punch, but this is not required.

Note 2 

When bottoming operation is selected, the end of bend position of the Y-axis beam depends  on the working force. 

If however the force is sufficient for the beam to go to the calculated Yaxis end of bend position, the beam stroke will be limited by the position value.

Bending length

Length of the sheet between tools

Effective bend length 

The effective length of the sheet between tools, which is used for the calculation of the  force and the crowning device (if present). 

This effective bend length is calculated from  the product geometry; 

for additional bends and simultaneous bends this calculated  value is the sum of the separate bend line lengths.

Product position 

The absolute position value of the product in the Z-direction. Left machine side is  reference position zero.

Angle 

The required angle of this bend. This parameter only appears if angle programming is  selected with the parameter 'Angle sel.' and the bend method is an air bend.

Hem opening 

The hem bend can be made with a certain opening distance between the 2 flanges. 

The  hem opening value will be used calculating the beam position in the hemming process. 

By default this parameter has the value of the Settings mode parameter Default Hem  Opening.

Y-axis (Bend position) 

The required Y-axis position for this bend. This parameter only appears if absolute  programming is selected with the parameter 'Angle sel.' 

This parameter also appears if  the bend method is bottoming and/or hemming.

Mute 

Sequence point at which the Y-axis is switched from fast closing speed to pressing  speed. 

The value programmed here is the distance of the mute point above the sheet.  By default, 

the mute value from the programmed die is used. 

Whether or not this parameter is present depends on machine settings.

Parallel 

Difference of left- and right hand side cylinder (Y1 and Y2). When positive, 

right hand  side lower. When negative, right hand side higher. The programmed value is active  below the clamping point.

Opening 

This parameter results in a certain gap opening between the punch and the die after the  bend. 

A positive value is the gap opening above Mute, a negative value below Mute. 

When you want to limit the handling time of the product you can program a small  positive or a negative value.

4.2.2. Force

Force 

Maximum adjusted force during pressing (automatically computed).

Dwell time 

Holding time of punch at bending point.

Decompression 

Decompression distance after the bending to release the working pressure from the  system.

4.2.3. Speed

Speed 

Working speed (pressing speed). Initially, the value for this parameter is copied from the  parameter Default Pressing Speed in the Settings mode.

Decomp speed 

The decompression speed is the programmable speed of the beam during the  decompression distance.

4.2.4. Functions

Repetition 

0 = bending is skipped 

1 through 99 = the number of times this bending will be repeated.

Wait for retract 

In case of a retract, let the Y-axis wait until the retract is finished, yes or no. 

No: the retract is started when the Y-axis passes the clamping point, the Y-axis does not  stop. 

Yes: when the Y-axis reaches the clamping point, the Y-axis is stopped and the retract  is started. When the retract is completed, the Y-axis moves on.

Code

Programmable step change code parameter which determines when the parameter  values for the next bending will be active. 

The following settings are possible: 

0 = ER: Bending number change (step change) at end of decompression (next bend  parameters active). 

1 = MUTE: Step change at muting position when the beam moves in opening direction. 

2 = UDP: Step change at upper dead point. 

3 = UDP STOP: Step change at upper dead point without movement of any axis and the  control goes to "stop". 

4 = EXTERNAL: Step change if C-input signal becomes active, without movement of the  beam. When you still have a beam movement there will be no retract function of the  back gauge performed. See also code 5. 

5 = UDP EXTERNAL: Step change if C-input signal becomes active and the beam is in  the upper dead point. Now you may move the beam and the retract function of the  back gauge will be performed.

Delay time 

Programmable delay time before step change (0-30sec)

4.2.5. Product properties

Thickness 

The thickness of the sheet.

Material 

The material of the product.

4.2.6. Tools

The set tools are displayed and can be modified from the Tool Setup menu. 

If required the  tools per bend can be specifically selected for that bend using Change Tools.

Punch 

The name (ID) of the selected punch. Tap Change Tools to modify or select from the  punch library.

Die 

The name (ID) of the selected die. Tap Change Tools to modify or select from the die  library.

Press the Change Tools button to get an overview of the available tools in the library

4.2.7. Auxiliary axes

Auxiliary axis 

The position of the selected axis. 

Retract 

Retract distance of the selected axis in the current bend. The "backgauge retract" is  started when the beam is pinching the sheet. 

Speed 

Speed of the selected axis in the current bend. Speed can be programmed in a  percentage of the maximum possible speed. 

Layon 

Toggle between lay surface on finger or not. This option is only selectable in case you  have an R-axis in your machine.

4.3. Edit / view modes

4.3.1. All Bends

When the function All Bends has been pressed, a complete overview of the bends appears.

From within this screen, the complete CNC program can be edited. 

All bend parameters can  be edited within the table and bends can be swapped, moved, added and deleted.

The available columns can be scrolled by finger movement / swipe.

Functions

Edit 

Edit the program with one of the following commands: 

• insert bend 

• mark bend 

• delete bend

When the function Edit has been pressed a new, temporary button bar appears with additional  functions:

+Insert Bend

To insert a new bend between one of the bends. When pressed, the current bend is copied  and added before the current bend.

+Mark Bend

Mark the current bend, in order to prepare it for another action, like move or swap. See  description below.

+Delete Bend

To delete the bend that is currently selected.

When a bend has been marked with the function key Mark Bend several other functions  become available:

+Move Bend

In the table overview of the bend sequence, it is possible to change the order of bends simply  by moving a bend to another place. 

Select the bend that must be moved. Then press the  button Mark Bend and the bend is highlighted. 

Now select the right place in the sequence.  When the correct bend is highlighted, press Move Bend. The bend will be inserted on the  current place.

+Swap Bends

With this command, two bends can change place in the bend sequence.

 Move the cursor to  one of the required bends and press the Mark Bend button.

 Then move the cursor to the bend  with which it must be swapped and press Swap Bends.

 If for any reason the action must be  cancelled, press the function Abort Mark during the procedure.

+Abort Mark 

Remove the mark from the currently marked bend.

A bend is no longer marked when the mark is aborted, when an action is finished or when this  menu is left.

Copy Column 

Copy the value of the currently selected parameter in the current bend to all other bends.

Chain Bendsteps 

Chaining of bend steps is possible by just setting the number of steps in the chain (Repetition)  and the backgauge position offset (X offset). 

The relative offset value can be positive as well  as negative for flexible chaining.

4.3.2. Change tools

To change the tools the Tool Setup menu can be used. If the tool setup needs to be changed  for just one bend step, the Change Tools button can be used. The control will always ask if the  changes are to be done on the whole setup or just for one bend. If the whole tool setup is  required, automatically the Tool Setup menu will be switched to.

4.3.3. Product properties

To change the main product properties tap Product Properties.

These parameters of the  program are the same for every bend of the program (main data of program).

Parameter explanation

Product ID

A unique name to identify a product program. The maximum length is 25 characters.  The product ID may contain letters and numbers.

Product description

A number or description of this program. The maximum length is 25 characters. The  product description may contain letters and numbers.

Angle sel.

Selection of the programming mode for the Y-axis. 

0 = absolute: program the absolute Y-axis position for a bend. 

1 = program the angle to bend. 

The required Y-axis position is computed. 

Depending on this parameter, either the parameter Angle or the parameter Bend  Position will appear in a bend step.

Thickness

Thickness of the sheet.

Material

Selection of one of the programmed materials, which are used to calculate the bending  depths. 

The control contains 6 pre-programmed materials. In total, 99 materials can be  programmed on the control. 

The materials can be programmed on the Materials page in  the Settings mode.

	Tensile  strength (N/mm²)	E-module (N/mm²)	Strain  hardening  exponent
1 = Steel  2 = Aluminium  3 = Zinc  4 = Stainless steel	470  250  200  750	210.000  210.000  94.000  210.000	0.23  0.26  0.20  0.32

Functions

Connect

The function Connect is to have a possibility to connect certain programs to each other. 

This  option can be used to produce 3-dimensional products out of two programs

+Connect program

With the function Connect it is possible to create a 3-dimensional product. 

The control  automatically executes the bend sequences in the different directions in succession. You  program the control as follows:

1 Create the product in one direction.

2 Create the product in the other direction.

There are now two bend programs of one product in two directions. You connect these  programs as follows:

1 Select the program with the bend sequence in the direction which you want to  execute in the first place. You select the program of the product via the ’product  library’. 

2 Go to the Program mode and select Product properties. 

3 In the Product properties window you select the function Connect and Connect  program. 

4 Select the product ID of the product in the other direction. 

5 Select the second program as in step 1. Repeat steps 2 to 4. If you want to connect two programs, as in this example, you enter the product ID of the first program. The cycle is closed.

When you want to execute more than two programs in succession (not necessarily to create a  3-dimensional product)

 the second program must refer to the third. 

The third program to the  fourth and so on. The final program of the cycle must always refer to the first program.

To produce products with connected programs the next four actions are necessary.

1 Select the first program 

2 Select the Automatic mode 

3 Program the amount of products you want to produce with the ’stock count’parameter. 

4 Push the Start key

When the first program has been finished the second program starts automatically. 

The  program counter indicates the remaining amount of repeats.

+Disconnect program 

To stop the sequence of connected programs. 

Save as 

Copy the current product. When pressed, you must enter a new product ID for the copy  program.

4.3.4. Add bend 

To add a new bend after the last bend. When pressed, the last bend is copied and added after  the last bend.

4.3.5. Bumping 

From pure numerical programs a single bend step can be changed into a bumping bend.

When Bumping has been selected in the Main view, a pop-up window is shown on which the  following parameters can be programmed:

Bumping

disabled => Air bend as normal bend with a defined angle and preferred radius. 

enabled => Large radius in different steps of airbending.

Angle 

The angle value to bend.

Radius 

The intended radius which is programmed.

Number of segments 

The number of segments in which the radius will be divided. 

The number of bends in this  radius is the number of segments plus 

1. The more segments you select, the more bends will be used to create the programmed  radius within a smaller tolerance. 

With a high number of segments you will need a  smaller V-die opening to be able to bend in a proper way

Equal bumping-segments

When a product has a radius bend, the segment size is computed from the number of segments, which has been defined by the user. Standard the first and last segment are  calculated half the size of the mid segments to obtain a better result. However, it can be  a problem selecting a die suitable to bend these small segments. Therefore the control  can calculate an equal size for all segments. This can be defined with this parameter.

• Disabled (no equal sizes)

• Enabled (equal sizes)

When Enabled all segments will have an equal size. 

When Disabled the calculation is including half size segments. 

If in this case a problem  with the size of the V-die opening is detected in the bend sequence determination, 

the  user is asked whether or not to select a re-calculation with equally sized segments.

Bumping corrections can be found in Automatic mode where the user is helped in distributing  the correction over the related bends.

4.4. Programming parameters 

Parameters in program mode can be programmed one by one. The effect of the parameter on  other parameters is automatically computed. The relation between parameters is visualized with a symbol and a background color.

When an information symbol is shown with parameters after an edited value, this parameter  was changed due to the last changed input.

A star symbol is shown with parameters if the value of the parameter differs from the  calculated value by the control. This can be helpful if a value is intentionally programmed  different or if the value of a parameter is limited by the parameters limits.

An error symbol is shown with parameters if the value cannot be correct according to the  currently programmed values. This, eg. when a hemming bend is programmed with no  hemming tools programmed.

5. Automatic mode

In auto mode with the active program, production can be started. 

After entering Auto, the Start  button can be pressed and production can begin.

The automatic mode executes the program automatically bend by bend after pushing the Start  button. 

When selecting a different product in Products mode, which is in the library and has  already been used for production,

one can immediately switch to Auto and start production. 

Every time after a different bending program is selected you must check your tools and tool  positions in your machine. 

This is also indicated with a 'check tools' warning message when  you enter the automatic mode.

In the header of the Auto mode screen the selected product is displayed along with the  product description. 

At the top of the screen the bend selector shows the available bends in  the program. 

By tapping the prefered bend the bend can be selected. The start button can be  pressed to start from this bend.

The details of the selected bend are shown in the available  views.

The repetition of a bend and the connected programs, when applicable, are shown in the  header of the screen. 

A connected program is also indicated in the bend selectors last  position.

5.1.1. Auto mode, parameter explanation

Following is a list of the available parameters in Auto mode.

Corrections

Angle 1 / Angle 2

Corrections on angle values in this bending. Angle corrections can be programmed for both sides of the machine, Y1 and Y2. When  correction Angle 1 is entered for one side, this value is automatically copied to the  correction Angle 2 for the other side. The correction for the other side can then be  changed. When both angle corrections have been entered, the resulting corrections for  Y-axis and parallelism are calculated. The corrections will be saved in the active  bending program.

The angle correction should be entered as following examples indicate: 

Programmed value of 90 degrees. Measured value of 92 degrees. 

-> Then it is required to program of correction of 

-2. Programmed value of 90 degrees. Measured value of 88 degrees. 

-> Then it is required to program a correction of +2

In case the angle correction database has been switched on, the control checks whether a  correction exists for this type of bend in the database. The result of this check is prompted in  the entry field:

• No stored correction. No correction has been found for this bend 

• Stored correction. A correction that matches the current bend has been found 

• Interpolated correction. A correction has been calculated (interpolated) based on other existing corrections

If a correction is entered, it will be stored in the database. At each next bend with the same  properties, this same correction will be offered. The angle correction database can be found on the Program Settings page in the Settings  mode.

Y1 / Y2

Corrections on the Y-axis positions, in case absolute programming is used or bottoming  is selected for a bend.

Auxiliary axis

Corrections on auxiliary axis positions in this bending. In case bend allowance is  activated (see the Settings mode) and a program has been entered in Program mode,  the X-axes correction values are the result of bend allowance calculation. The corrections will be saved in the active bending program.

The auxiliary axis correction should be entered as following examples indicate: Programmed value of 200 millimetres. Measured value of 202 millimetres.

-> Then it is required to program a correction of -2. Programmed value of 200 millimetres. Measured value of 198 millimetres. 

-> Then it is required to program a correction of +2

deflect

Correction on the crowning device. Only available if a crowning device is present

General corrections

Thickness

General correction on the product thickness, valid for each bend of the program.

Angle / Angle 2

General correction of the angle, valid for each bend of the program. 

The value should be  programmed in the same manner as for the correction per bend.

Depth

General correction on the Y-axis position, in case ’absolute programming’ is used and  ’air bend’ is selected for a bend. 

This correction is valid for each bend of the program.

X-axes

General correction of the X-axis position, valid for each bend of the program. 

The value  should be programmed in the same manner as for the correction per bend.

deflect

General correction on the crowning device. Only available if a crowning device is present.

General

Stock

The stock counter is incremented or decremented after each end of a program cycle.

Repetition

Selection of one of the repeated steps of one bend. Useful if a bend has a repetition  value larger than 1. This parameter is visible when the parameter Repetition in Program  mode has been set to a value larger than 0.

Step mode

Select to use either Auto mode (no) or Step mode (yes). In Step mode you have the  same possibilities as in Auto mode. 

There is only one difference. After each bend cycle,  the control will stop. 

To continue working, you must start the control again by pressing  the Start button on the front panel of the control.

5.2. View modes

The auto mode screen is offering a diversity of views which, depending on ones production  methode, can be chosen.

When selecting auto mode for the first time, the main screen will  appear.

On the right side of the screen the available view modes can be selected.

Following view modes are available:

The appropriate view can be switched from and to, not changing the bend data. The Start will  not jump to Stop while switching view modes.

5.2.1. Main

Main view shows the numerical data of the bend along with the corrections. The corrections  can be programmed here.

Both columns can be scrolled to see all data.

Bend selector

The bend selector in the top of the screen can be used to navigate thru the bends.

The  indicated bends can be tapped to easily select the desired bend data.

5.2.2. All bends

The all bends view mode shows a table including all bend data. The bends are shown row  wize and the columns display all bend parameters.

5.2.3. Macro

With macro view mode, the control switches to a view with only large axes values on the  screen. 

This view can be used when working a little remote from the control, still able to read  the axes values.

Next to the target position (programmed) also the actual position of all axes can be followed

5.2.4. Manual positioning

In manual positioning view mode the axes values are shown at large. 

Axes can be selected  and while selected the position can be controlled by moving the slider, 

on the bottom of the  screen, out of its middle position. When releasing the slider it will return to its middle position  automatically.

The teach indicator:

When the teach indicator arrow is pressed, standing in between actual value and programmed  value, the value is tought to the program step.

5.2.5. Corrections

In this view mode all corrections of all bends are shown. You can browse through all  corrections and change them as you see fit. 

If a correction for 1 is entered then this value is,  dependent on the settings parameter 'Angle correction programming', copied to the correction  for 2, or keeping the delta between both corrections, or not influencing the correction for 2.  Different corrections for 2 can be entered in the field itself.

The column 'Stored correction' is only available when the Angle correction database has been  activated. When activated, the column 'Stored correction' shows for each bend the correction  value that is present in the database. A blank entry in this column means the database does  not have a correction value for this type of bend. When a new correction is entered, it will be  copied to the database automatically. 

The markers '>' indicate bends that have the same value. All From Stored serves to copy corrections in the database to the current program: corrections  in all bends are adjusted according to database values.

Calculate corrections, programming of measured angles

To calculate the corrections from measured angle values, one can use the “calculate  corrections” function in the correction window. 

Calculate corrections will open a separate  window in which, upon choice, the measured angle(s) can be programmed.

From the programmed value the control will determine a correction. 

The proposed result can  be seen in the window itself. In the top of the window the programmed angle is shown, 

in the  bottom of the window the resulting corrections are shown. When selecting accept, these  values will be transferred to the main corrections screen.

When only one measured angle value is entered, the other values will be copied equally.

 If  there are separate left, right or even middle values, these can be entered as well.

 The  appropriate correction values will be determined from the entered values. 

The middle  measured angle, if applicable, is transferred to an absolute crowning correction.

Axes corrections can also be edited in the main screen. When there are multiple axes  available this 

special view mode can be switched to for all axes corrections.

5.2.6. Diagnostics

The diagnostics view mode is meant for service purpose mostly. 

In diagnostics the activities of  independent axes can be monitored. I/O on the control system can be followed. 

In rare  situations this information can be helpful to diagnose operation during the bending proces.

5.3. Bumping correction

In case of a selected bumping bend a general correction for a bumping bend can be entered. 

This function is only available if a product is loaded that contains a bumping bend. 

With Bumping Corr. a new window appears in which the correction can be entered.

When the general correction of an angle is altered, all individual corrections are recalculated.  When any of the individual corrections is altered, the general correction is recalculated. Bumping corrections can be programmed independently for both sides, 1 and 2. If a bumping correction for 1 is entered then this value is, dependent on the settings  parameter 'Angle correction programming', copied to the bumping correction for 2, or  keeping the delta between both bumping corrections, or not influencing the bumping  correction for 2. Subsequently all separate corrections for 2 are recalculated. To change  correction values of 2, use bumping correction 2 or one of the separate corrections of 2.

6. Manual mode

6.1. Introduction

In manual mode you program the parameters for one bending. This mode is useful for testing,  for calibration and for single bends.

Manual mode is independent from Automatic mode and can be programmed independently of  the programs in memory.

In the top of the Manual mode screen you can find the Y-axis and the main X-axis current  position. All other axes and functions are listed one by one in the two columns below. When these Y-axis value and X-axis value are highlighted it means that the reference markers  of these axes have been found and that they are positioned correctly referred to their  programmed values.

6.1.1. Manual mode, parameter explanation

Following is a list of the available parameters in Manual mode.

Bend parameters

Method

Select the required bending method. The control supports the following standard  methods: 

• Air bend 

• Bottoming 

• Hemming 

• Hemming & bottoming

The bend methods have been explained in more detail in the Program mode.

Bending length

Program the bending length of the sheet.

Product position

The absolute position value of the product in the Z-direction. Left machine side is  reference position zero.

Angle

Angle to bend

Corr. 1, Corr. 2

Correction on angle to bend.

The angle correction should be entered as following examples indicate: Programmed value of 90 degrees. 

Measured value of 92 degrees.

-> Then it is required to program Corr. with 

-2. Programmed value of 90 degrees. Measured value of 88 degrees. 

-> Then it is required to program Corr. with +2.

Hem opening

The hem bend can be made with a certain opening distance between the 2 flanges. The  hem opening value will be used calculating the beam position in the hemming process.  By default this parameter has the value of the Settings mode parameter Default Hem Opening.

Corr.Y

Correction on the Y-axis position, in case bottoming has been selected

Y-axis

The programmed or calculated Y-axis value to realise a certain angle.

Mute

Sequence point where the Y-axis is switched from fast closing speed to pressing speed.  It is programmed here as a Y-axis position value. The programmed value is the Y-axis  point above the sheet.

Parallel

Difference of the left- and right hand side cylinder (Y1 and Y2). When positive, the right  hand side is lower. When negative, the right hand side is higher. The programmed value  is active below the clamping point.

Opening

This parameter results in a certain gap opening between the punch and the die after the  bend. A positive value is the gap opening above Mute, a negative value below Mute.  When you want to limit the handling time for the product you can program a small  positive or a negative value.

Force

Force

The programmed force applied during pressing.

Dwell time

Hold time of punch at the bending point

Decompression

Decompression distance after the bending to release the working pressure from the  system.

Speed

Speed

Pressing speed, the speed of the Y-axis during bending.

Decomp speed

The decompression speed is the programmable speed of the beam during the  decompression distance.

Functions

Wait for retract

In case of a retract, let the Y-axis wait until the retract is finished, yes or no. No: the retract is started when the Y-axis passes the clamping point, the Y-axis does not  stop. Yes: when the Y-axis reaches the clamping point, the Y-axis is stopped and the retract  is started. When the retract is completed, the Y-axis moves on.

Product properties

Thickness

Program the thickness of the sheet.

Material

Selection of one of the programmed materials, which are used to calculate the bending  depths. The control contains 4 pre-programmed materials. In total, 99 materials can be  programmed on the control. The materials can be programmed on the Materials page in the Settings mode.

Tools

Punch

The name (ID) of the selected punch. Tap to modify or select from the punch library

Die

The name (ID) of the selected die. Tap to modify or select from the die library.

Auxiliary axes

Auxiliary axis

If you have one or more auxiliary axes (for instance an X-axis, R-axis or Z-axis) the  parameters of these axes appear here.

Retract

The retract distance of the axis during the bend. The "backgauge retract" is started at  the pinching point.

Speed

Speed of the axis in the current bend. Speed can be programmed in a percentage of the  maximum possible speed.

The above mentioned parameters can be programmed and modified as required. After  pushing the Start button the programmed parameters are active.

6.1.2. Tool setup

The programming of the tool setup in Manual mode is similar to programming the tool setup  which is used in Automatic mode. Despite the fact that both modes do not share the same tool  setup (enabling the usage of a complete different tool setup), the tool setup of Automatic  mode could be used in Manual mode as well. While switching from Automatic mode to Manual mode, the control offers the user to use the  same tool setup in Manual mode and thus also the user is warned that in case differently  programmed, one should be careful.

In the tool setup menu tools can be added or removed, similar to the main Tool Setup mode as  described in chapter 3.

Adding tools ( Punches / Dies ) 

Same as in Tool Setup, via the Add function tools can be added.

6.2. Programming parameters & Views

Parameters in manual mode can be programmed one by one. The effect of the parameter on  other parameters is automatically computed. The relation between parameters is visualized with a symbol and a background color.

When an information symbol is shown with parameters after an editted value, this parameter  was changed due to the last changed input.

A star symbol is shown with parameters if the value of the parameter differs from the  calculated value by the control. This can be helpful if a value is intentionally programmed  different or if the value of a parameter is limited by the parameters limits.

An error symbol is shown with parameters if the value cannot be correct according to the  currently programmed values. This, eg. when a hemming bend is programmed with no  hemming tools programmed.

View 

The command buttons on the right side of the screen give access to other views. Next to the Main view, there are Macro, Manual Positioning, Corrections as also a Diagnostics view.

6.3. Macro

With Macro the control switches to a new view with only large axes values on the screen. This  view can be used when working a little remote from the control, still able to read the axes  values.

6.4. Manual movement of the axes

6.4.1. Movement procedure

To move an axis to a specific position manually, the slider at the bottom of the screen, can be  used. After tapping Manual Pos in the main screen of Manual Mode, the following screen  appears:

Within this mode, any of the shown axes can be moved by moving the slider out of its middle  position. The procedure for moving the axis depends on the axis you wish to move. When  releasing the slider it will automatically return to its middle position.

Auxiliary axes

The control must be stopped (the Stop button is on). 

First select the desired back gauge axis, you will see the cursor at the required axis. 

Then you can move the axis by moving the slider.

Y-axis

The pressbeam can be positioned manually in the same way as the auxiliary axes.

However, for the Y-axis several conditions must be met: 

• The control must be started (the Start button is on). 

• The 'adjust' function must be active. If this function is not active a message is  shown in the upper right-hand corner. 

• The Y-axis must be below mute-point. 

• A pressing command must be given to the CNC.

6.4.2. Teach

To teach the control, taking over a position found by manual moving an axis, a simple  procedure can be used. When you have moved an axis to a certain position with the slider, you may want to store this  position. To do so, tap the axis name in the Programmed column. The actual axis value (left  side) will appear in the programmed axis field (right side).

When you return to the standard screen of manual mode, the axis parameter will have the  recently taught value.

6.5. Corrections

In this view mode the corrections for the bend programmed in Manual mode are shown. Since  this is always a single bend, a single line will be shown.

The programmed corrections can be verified here similarly to the corrections in Automode.  Entries in the correction database and for initial correction can also be monitored in this  screen. Since these are of significant influence on the bend result, access to the database can  be used to modify. This can also be useful while finding appropriate corrections with  testbending and storing the found results in the database.

6.6. Diagnostics

When tapping Diagnostics, the control switches to a view which shows axes states. In this  window, the current state of available axes can be observed. This screen can also be active  while the control is started. As such, it can be used to monitor the control behaviour during a  bend cycle.

6.6.1. IO status

When tapping on the I/O tab in the Diagnostics, the control switches to a view with the state of  inputs and outputs. In this window, the current state of inputs and outputs can be observed.  This screen can also be active while the control is started. As such, it can be used to monitor  the control behaviour during a bend cycle.

Zoomed IO

When tapping on one or more (up to 5) pins an extra page Zoomed IO is created with an  enlarged view of the selected IO; selected pins will be shown in large, enabling distant  monitoring.

7. Settings

7.1. Introduction

The Settings mode of the control, which can be found in the navigation panel, gives access to  all kind of settings which influence the programming of new products and programs. Default values and specific constraints can be set.

The settings are divided across several tabs logically organizing the different subjects. In the  following sections the available tabs and detailed settings are discussed.

Navigation through the tabs can be done by just tapping them and selecting the required item  to adjust. Since there can be more tabs than the screen can show in one view, dragging the  tabs in horizontal direction enables to view and select all available tabs.

7.2. General

Select the required tab and tap the parameter to be changed. When parameters have a  numerical or alphanumerical value, the keyboard will appear to enter the desired value. When  the setting or parameter can be selected from a list, the list will appear and selection can be  done by tapping. Longer lists allow scrolling vertically to check the available items.

Inch/mm-select

Select to use either millimeters or inches as the unit to be used.

Ton/kN select

Select to use either Ton or kN as the main unit to be used for all force data.

Resistance per m/mm selection

Select to use the resistance either per meter or per millimeter.

Language

The user interface language can be selected from the list. There are more available  languages than initially shown. Scroll vertically by dragging the list up en down to see all  available languages. Tap to select the desired language for the user interface.  (For languages using special, non standard alphanumerical characters, the control will  reboot.)

Keyboard layout

Upon choice one can select Qwerty, Qwertz or Azerty keyboard layout.

Key sound

Switch the sound function of the input panel on or off.

Message sound

Parameter to enable/disable the sound function for messages dependent on the  message type.

all messages => sound on for all messages. 

errors + warnings=> sound on for errors and warnings only. 

errors => sound on for errors only.

none => sound off for all messag

Command panel side

Switch the command panel to the left side of the screen.

7.3. Materials

In this tab, materials with their properties can be programmed. Existing materials can be  edited, new materials can be added or existing materials deleted. A maximum of 99 materials  can be programmed on the control.

For each material 3 properties are present and can be viewed and edited.

Material name

Name of the material, as it will appear in the programming screens. The maximum  allowed length of the material name is 25 characters, the name must begin with a  character (not a numeral).

Tensile strength

Tensile strength of the selected material.

E module

E-module of the selected material.

Strain hardening exponent

The Material strain hardening exponent, n, is a material property that should be  provided by the supplier of the material, just like the tensile strength and E-module. Entering the correct values for this parameter will give an improvement of the inner  radius calculation and thus a more accurate bending depth and bend allowance  calculation. In its turn a more accurate bend allowance will result in more accurate back gauge  positions. Initially the value is set to _.__ for all the materials. This means that the parameter n is not active. The result of all calculations is the same as with previous software versions.

The range of the parameter n is 0.01 – 1.00. For example, a typical value for mild steel is 0.21. When 0 is entered again, the value will be reset to _.__

Calculate n

The Material strain hardening exponent, n, is a material property that should be provided by  the supplier of the material, just like the tensile strength and E-module. As an alternative, it can also be derived from the bend allowance. A test bend has to be made  in Manual mode. When you switch to the materials table and tap the button ‘calculate n’, the  following window will appear on the screen:

The parameter values are taken from the Manual mode screen. After the bend the resulting  side length should be measured and entered in the window. With the difference between the  programmed X-axis position and the measured side length the bend allowance and the strain  hardening exponent (n) are calculated. The accuracy of the calculation depends on the accuracy of the sheet thickness, tool  parameters and side length measurement.

The materials are initially listed according to their material number, which is shown in the first  column (ID). The list can be sorted according to the different properties by tapping the title of  the column. The materials will be sorted in ascending or descending order of that property

To change an existing material, select the relevant line and change the values as you see fit.  To delete an existing material, select the relevant line and use Delete Material. This will erase  the values.

To program a new material select an empty line and start programming its values.

7.4. Backup / restore

This tab offers the possibilities to backup and restore products, tools as well as settings and  tables. When products or tools originate from older control models, the DLC-file format  products and tools can also be restored using this specific restore function. For materials a specific backup and restore are available here.

Tools and products can be backupped and restored according to the following procedures.  The procedures for saving or reading data are similar for all types of backup media: e.g.  network or USB stick.

The actual backup directory consists of a device (USB stick, network) and a directory. The  choice of devices depends on which devices have been connected to the control. If  necessary, directories can be created and selected. The backup locations for storage of  products and tools can be set independently.

7.4.1. Product backup

To make a backup of programs to disk, choose ‘products’ in the Backup section on the  Backup/restore page.

When the initial backup directory has been set, the products backup screen appears.

In the backup screen the products in the selected directory are shown.  Basic functions to change the view can be chosen similarly to the Products mode. This  enables to easily find the required products to be backupped.

At the top of the screen, the current source location is shown as well as the backup location.  To backup a product, select it by tapping, in the list. The backup marker will appear to confirm  the backup action. If a product file with the same name is present on the backup location, a  question is offered whether or not to replace that file.

To backup all products at ones, tap All.

The source where the products are located which have to be backupped can be changed with  Source Directory. The directory browser appears and the desired source directory can be  navigated to.

The directory where the products which need to be backupped need to go can be changed as well. With Backup Directory the directory browser appears and the desired destination  directory can be navigated to.

7.4.2. Product restore

To restore programs to the control, choose ‘products’ in the Restore section on the Backup/ restore page.

When the initial restore directory has been set, the products restore screen appears.

In the restore screen the products in the selected directory are shown.  Basic functions to change the view can be chosen similarly to the Products mode. This  enables to easily find the required products to be restored.

At the top of the screen, the current restore source location is shown as well as the location on  the control to restore to. To restore a product, select it by tapping, in the list. The restore  marker will appear to confirm the restore action. If a product file with the same name is  present on the control, a question is offered whether or not to replace that file.

The source location where the products to be restored are coming from can be changed with  Restore Directory. The directory browser appears and the desired restore directory can be  navigated to.

The directory where the products which need to be restored need to go can be changed as  well. With Destination Directory the directory browser appears and the desired destination directory can be navigated to.

7.4.3. Tool backup

To make a backup of tools to disk, choose ‘tools’ in the Backup section on the Backup/restore  page.

When the initial backup directory has been set, the tools backup screen appears.

With this menu a back-up of tools on the control can be made: punches, dies or machine  shapes. The procedures for a tool back-up run similar to the procedures for a product backup.

7.4.4. Tool restore

The restore procedures for tools run similar to the procedures for a product restore.

7.4.5. Backup and restore for Tables and Settings

To backup user specific settings and tables the Backup/restore tab offers specific  functionality. The procedure is again similar to the backup and restore of products and tools.  The special function All will automatically execute all steps sequentially for either Backup or  Restore (Products + Tools + Tables + Settings).

7.4.6. Directory navigation

When Backup Directory is used, a new window appears with a list of available backup  directories.

In this window you can browse through the directory structure of your backup device. To  select the directory you are currently in, tap Select.

To change from one device to another, tap the highest level, and from there select the proper  device and choose the correct subdirectory.

If a network connection is available you must first select Network and subsequently one of the  offered network volumes. After that it works similar to other devices.

You can make new subdirectories or delete existing ones by tapping Make Subdir and  Remove Subdir. If there are subdirectories present, just tap it to move to the required directory  and tap Select to select it.

7.5. Program settings

Angle correction database

Parameter to enable the database with angle corrections.

Angle corrections are entered in production mode (Automatic mode). These corrections  are stored in the product program.

The Angle correction database enables the possibility to store these corrections in a  database. In this way corrections that have once been entered for certain bends remain  available for future use in other products.

With this setting enabled, the control checks during production whether corrections for  similar bends are present in the database. If corrections for certain bends are available,  then they will be offered. On other occasions, corrections can be interpolated and  offered. 

The correction database is adjusted by entering new corrections during production.  When the database is enabled with this parameter, all new-entered corrections are  stored in the database.

When searching for similar bends, the control searches for bends that have the same  properties as the active bend. The following properties of a bend are compared:

• Material properties 

• Thickness 

• Die opening 

• Die radius 

• Punch radius 

• Angle

The first five properties of a bend must be exactly the same as the active bend to start a comparison. If the angle is the same as the angle of the active bend, the correction is  offered. If the angle of the active bend has a maximum difference of 10° with two  adjacent bends, a correction is interpolated from these two bends. If the difference of  the corrections of the two adjacent bends is more than 5°, there will be no correction  offered.

Initial angle correction

To program relative small angle corrections the initial correction database is available.  This parameter is independent on the parameter "Angle correction database".  The initial correction is only visible and programmable on the corrections page in  Automatic mode and Manual mode. On the main page in Automatic mode and Manual  mode the initial correction is not visualized. The total correction is the sum of the  visualized correction and the initial correction.

Example: 

- Program an angle correction of -8 degrees. 

- Program an initial correction of -6 degrees. 

Now the total correction  remains unchanged:

 the visualized correction is changed from 

-8 degrees  to -2 degrees.

disabled => no initial angle corrections programmable. 

enabled => initial angle corrections programmable on the corrections page

General angle correction programming

To program general angle corrections which are used in all bends of the program. These angle corrections are not related to specific bend angles and therefore not stored  in the angle correction database.

disabled 

=> no general angle corrections. 

enabled 

=> only G-corr. 

1. 1 and 2 

=> G-corr. 1 and G-corr. 2.

Manual mode store angle corrections

To enable the storage of angle corrections programmed in Manual mode. Corrections  can be derived from bend results in Manual mode which later can be used during  product programming.

Angle correction programming

Parameter to switch between copying or keeping the delta values or changing  independently when changing angle corrections in production mode.

copy     => copy C1 to C2 when changing C1. 

delta     => keep delta between C1 and C2 when changing C1. 

independent    => change C1 and C2 independently.

X correction programming

Parameter to switch between copying or keeping the delta values or changing  independently when changing the X-axis corrections in production mode.

copy      => copy CX1 to CX2 when changing CX1.

delta     => keep delta between CX1 and CX2 when changing CX1.

independent     => change CX1 and CX2 independently.

Only available when an X2-axis is present.

Y1/Y2 independent

Parameter to program the two Y-axes independently.

off     => single Y-axis programming.

on     => program Y1 and Y2 separately

Machine ID

When there are several bending machines in a factory, it can be useful to give the  control on each machine a unique machine ID. 

This ID will be checked when a program is read from a back-up medium. When the  machine ID does not match you must confirm to read it anyway or not. If you do not  confirm the question the action will be aborted.

Machine ID check

When a product from a machine with a different machine ID is selected, a warning will  appear on the screen. With this parameter this check can be disabled.

Machine description

The description as programmed here will only be used in the offline Profile-T to get an  overview of the different machines available in the factory. With this information it will be  more clear which machine is used in combination with this control.

7.6. Default values

Y opening default

Default Y-axis opening, used as initial value for the parameter 'opening' in a new  program.

Default pressing speed

Default pressing speed, used as initial value for the parameter 'speed' in a bend  program.

Default decompression speed

Default decompression speed, used as initial value for the parameter 'decompression  speed' in a bend program.

Default wait for retract

Default value for the parameter 'wait for retract' in a bend program. This parameter  determines the control behaviour in a bend program.

Default step change code

Default value for the parameter 'step change code' in a bend program. This parameter  determines the moment of step change in a bend program. The step change codes have been explained in more detail in the Program mode.

Default delay time

During the postprocessing, the waiting time of the X-axis at step change is set to zero.  With this parameter you can preset a longer waiting time when needed for product  handling.

Default dwell time

Default value for the parameter 'dwell time' in a bend program.

Default hem opening

The hem bend can be made with a certain opening distance between the 2 flanges. The  hem opening value will be used calculating the beam position in the hemming process.  This programmed default value will be used when programming a new program in the  Program mode. The starting value is 0.0mm to get the two flanges of a hem bend  completely upon each other without any space between the flanges.

Default material

Default material, used as initial selection while starting a new program.

7.7. Computation settings

Data preparation bend allowance

correction off => no bend-allowance added to numerical programming

correction on => bend-allowance correction added to numerical programming

With this parameter you can choose whether or not you wish to have programmed

values corrected for bend-allowance. This setting only refers to corrections during

product programming in the Program mode. If a numeric program has been entered with

Corrections On, the axis corrections are calculated and stored in the program. These

corrections can be viewed and edited in production mode (see 'Auto mode').

Bottoming force factor

The force needed for an air bend is multiplied by this factor in order to obtain the  bottoming force.

Z-distance

The distance from the edge of the finger to the corner of the sheet. When an automatic Z-axis has been installed, the positions of the fingers are calculated automatically with respect to the end of the sheet.

7.8. Production settings

Stock count mode

Setting for the stock counter in production mode, to have the stock counter (product  counter) count up or down. When down counting is selected, the stock counter in production mode is decremented  after each product cycle. When the counter has reached zero, the control is stopped. On  the next start action, the stock counting value is reset to its original value. When up counting is selected, the counter is incremented after each product cycle. Down counting can be useful if a pre-planned quota must be produced. Up counting  could be used to give a report on production progress.

Auto bend change mode step

This parameter can be used to have automatic step change in the bending process with  the Step mode enabled.  disabled => No automatic step change (next bending parameters active) will take  place. To perform the next bending you must select the new bending and press the start  button. enabled => The next bending parameters are loaded automatically but the axes  will start positioning after the start button has been pressed.

Parallelism offset

An overall parallelism, valid for the complete Y-axis stroke, can be programmed with this  parameter. The programmed value will be checked against the maximum allowed value  during production. The parallelism which can be programmed for each bending (Y2) is  only active below the clamping point. The parallelism below the clamping point is the  sum of the two parameters (Y2 + Parallelism offset).

Lock touch screen when started

To enable the locking of the touch screen while the control has been started.

Pressure correction

Percentage of calculated force which actually controls the pressure valve.

Clamping correction

The position of the beam at which the sheet is clamped, is calculated. In order to have a  firm clamped sheet it is possible to offset the calculated pinch point with the value here  programmed. A positive value will result in a deeper position, a negative value in a  higher position of the beam.

X-safety offset

Defines the safety zone (minimum X-axis value), following the contour of punch and die,  which will be used in case a R-axis is mounted. This to prevent collision between finger  and punch / die.

Intermediate X for Z-movement

Temporary safe value for the X-axis, to avoid collision as a result of movement along the  Z-axis. With this parameter a standard safety zone for the X-axis is defined, which is  valid for all programs. The value 0 disables this functionality. This parameter should not  be confused with the parameter ’X-safety offset’. This parameter is especially useful when several dies of different sizes are placed on  the machine. In that situation, this intermediate X-value should be larger than the safety  zone of the largest die that is installed.

When the back gauge has to move to a different Z-position, it is checked whether the current  X-position is safe. We can distinguish the following situations:

• Old X-axis position as well as new position outside the zone: X- and Z-axis movements  happen at the same time, no change. 

• Old X-axis position outside, new position inside the zone: back gauge is positioned on  Z-axes first, the X-movement starts when the Z-axes are in position. 

• Old X-axis position inside, new position outside the zone: back gauge starts along Xaxis, Z-movement is started when X-axis is outside the zone. 

• Old X-axis position as well as new position inside the zone: back gauge moves to the  intermediate X-axis position, then the Z-movement is started. When the Z-axes are in  position the X-movement is started to move the back gauge to its new position.

Intermediate R for X-movement

Temporary position for the R-axis, to avoid collision as a result of movement of the Xaxis. The value 0 disables this functionality. When programmed not equal to zero this position will be active when the X-axis has to move inside the safety zone of the die.

The sequence will be as follows:

• The R-axis is moved to the intermediate position; 

• then the X-axis is moved to its intended position; 

• finally the R-axis is moved to its intended position.

The safety zone of the die is defined as follows:

SZ = X-safe + SD

Explanation:

SZ = safety zone 

X-safe = safety zone of the die 

SD = safety distance, defined by machine supplier

8.1. Introduction

The Machine mode of the control, which can be found in the navigation panel, gives access to  the configuration items of the machine and specific machine characteristics which influence  generic calculations and machine behaviour.

The settings are divided across several tabs logically organizing the different subjects. In the  following sections the available tabs and detailed settings are discussed.

Navigation through the tabs can be done by just tapping them and selecting the required item  to adjust. Since there can be more tabs than the screen can show in one view, dragging the  tabs in horizontal direction enables to view and select all available tabs.

8.2. Programming of Punches

In this tab, the punches used in the machine can be programmed. New punches can be  added; existing punches can be edited, copied, renamed and deleted.

8.2.1. Create a new punch

To create a new punch, tap New in the library. The punch profile can be created with help of  the programming facilities of the control.

First the shape of the punch and its ID must be programmed. After that the shape details must  be programmed following the wizard.

Shape

A selection must be done from the different available basic punch shapes corresponding  to the required punch action. Options are: • Standard Punch shape as normally used for air bending and basic bottoming. 

• Hem Bend Punch as typical tool with flat bottom for specific hem bends. 

• Air + Hem Bend Punch as tool for normal air bends and hem function. 

• Big Radius Punch shape especially for big radius bends.

ID

A unique name or number to identify the tool. The maximum length is 25 characters.

The ID parameter may also contain alphanumeric characters. When finished, use Accept to  leave this window and start with the tool data parameters. The control will prompt a window for  the tool properties with the dimensions of the tool.

Depending on the chosen basic shape, the parameters will differ. In the following paragraphs  the available punch shapes are described in detail.
