The calculation of the roll forming steps is done accordingThe basics of roll form tooling design,You can successfully roll-form a profile more than one way. In fact, many roll form designers take different approaches to design and development. Also, because the roll forming process has a seeming limitless capacity to produce complex profiles with just as many variables, many roll form designs are one-of-a-kind; therefore, theory can go only so far.
