How to Calculate Press Brake Tonnage

P = 1.42 x sigma x L x T^2 / V

FAQ

What tonnage press brake do I need?

Use the calculated value as a baseline and add a process safety margin for production variation, tooling condition, and future jobs.

How to calculate bending force?

Bending force usually depends on material strength, thickness, bending length, and die opening. This calculator applies standard engineering equations.

Why is stainless steel harder to bend?

Stainless steel has higher tensile strength and springback, so it requires higher force and often stricter process control.
