The basics of roll form tooling design

The angles show how much forming is being done at each pass. If end flare is a concern and you want a finish pass, consider adding two more passes to this 10-pass example. Pass No. 11 would unfold bend No. 1 to about 86 degrees, and pass No. 12 would re-form bend No. 1 to the finished angle of 90 degrees.
