What does this calculator do?
Estimates the air-bending force for a straight bend from material factor, sheet thickness, bend length and V-opening.
Which inputs are required?
- Material or material factor
- Sheet thickness
- Bend length
- V-opening
Output: Estimated press force in tonnes
Formula or planning rule: F (tonnes) = 0.065 x thickness^2 x bend length / V-opening x material factor
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 Bending Force Calculator calculate?
Estimates the air-bending force for a straight bend from material factor, sheet thickness, bend length and V-opening. The result is estimated press force in tonnes.
Can the Bending Force 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.
