What does this calculator do?
Estimates punch-to-die cutting clearance from material and thickness.
Which inputs are required?
- Material
- Thickness
- Clearance coefficient
Output: Recommended total or per-side clearance
Formula or planning rule: Clearance = thickness x material coefficient
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.
