What does this calculator do?
Estimates force for punching a defined perimeter through sheet material.
Which inputs are required?
- Cut perimeter
- Material thickness
- Shear strength
Output: Estimated punching force
Formula or planning rule: F (tonnes) = 1.3 x perimeter x thickness x shear strength / 9800
How should the result be verified?
Check the selected tool's load rating, the press brake capacity and working length, the actual material data and the bend method. Use a controlled first piece and measure the released part before approving production.
