LaserCheck Angle Measurement System

Lasercheck For Press Brake

Manufacturing sheet metal parts with accurate bending angles that are kept constant all times often meets a problem during the actual production process: different parameters in material thickness and stresses. In order to solve this problem and to make use also of minor quality materials safe for the user, data M Engineering has developed a powerful solution for measuring bending angles in press brakes - the LaserCheck. LaserCheck enables the user to determine the exact bending angle for press brakes by using laser triangulation together with strain gauges - and it works contactless.

LaserCheck-Bending Angle Measurement System

Calibration & Accurarcy

The sensor accuracy is better than ±0.1°. The bending accuracy is influenced by the control, the machine accuracy, the tools and the material. Bending accuracies of ± 0.3° are typically achieved. To increase the bending accuracy the sensors can be calibrated after mounting, so the mounting tolerance is reduced.

All sensors are pre-calibrated in order to work with reasonable results also without calibration. Only the mounting angle must be defined. Linear error corrections can be input for different measuring situations by the machine user.
