What does this calculator do?
Estimates guillotine shearing force and a preliminary blade-gap reference.
Which inputs are required?
- Thickness
- Cut length
- Shear strength
- Blade angle
Output: Estimated shearing force and blade gap
Formula or planning rule: F (tonnes) = thickness^2 x length x shear strength / (2 x tan(blade angle) x 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.

Frequently asked questions
What does the Shearing Force Calculator calculate?
Estimates guillotine shearing force and a preliminary blade-gap reference. The result is estimated shearing force and blade gap.
Can the Shearing 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.
