Punching Force Formula: Quick Answer How to Calculate Punching Force Use the basic formula first: F = L × t × τ For a circular hole: L = π × d Where: - d = hole diameter, in mm- L = hole perimeter, in mm- t = sheet thickness, in mm- τ = material shear strength, in MPa or N/mm²- F = punching force, in N If only tensile strength is available, use a verified material-data source or a conservative… Read More »Punching Force Calculator: Formula, Tonnage & Sheet Metal Examples
