Force required to bend sheet metal with a bending brake

  1. Sep 29, 2015 #1
    I want to know the force required to bend a piece of sheet metal in a hand bending brake. The sheet metal is clamped down and then bent upwards to a desired angle. The action is performed in the video below . Let's say I wanted to bend a piece of .032" thick AL 3' long to 110° (given the brake was able to make this degree of bend). How much force would be required to make this bend using this bending method?

    "How much force?" Depends on the actual bend radius, how sharp an "edge" you have on the break.

    "Edge" is a radius of .04" And the bend radius is .045".

    What's the volume of metal in the bend that is being permanently deformed?

    times 2pi/4
    Don't think so.
