What does this calculator do?
Estimates the amount subtracted from outside flange dimensions to obtain flat length.
Which inputs are required?
- Bend angle
- Inside radius
- Thickness
- K-factor
Output: Bend deduction
Formula or planning rule: BD = 2 x OSSB - BA
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.
