Bend calculator
Choose the material, sheet thickness and bend length. You get the V opening, the force the bend needs, dies that match your clamping and the compact machines that can make it.

Compact machines for this bend
Air bending to 90 degrees with V about 8 times the sheet thickness. Force F = 1.42 x Rm x t² / V. These are rule-of-thumb values; check the load rating on each die page and ask us if you are close to a limit.
A part the calculator can't answer?
Send the drawing and your press brake model. We suggest the punches and dies for each bend.
