What does this calculator do?
Plans the number, spacing and angular increment of small bends used to approximate a large radius.
Which inputs are required?
- Target radius
- Arc angle
- Material thickness
- Preferred pitch
Output: Bump count, pitch and bend increment
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.

Frequently asked questions
What does the Bump Bending Calculator calculate?
Plans the number, spacing and angular increment of small bends used to approximate a large radius. The result is bump count, pitch and bend increment.
Can the Bump Bending Calculator approve a production setup?
No. It is a preliminary planning aid. Verify the result against the machine manual, tooling load chart, material certificate, safety requirements and a controlled test bend.
