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.
