Conclusion: Roll pass design not only aims to improve the size, shape and mechanical properties of the rolled products but also it seeks to optimize the roll pass process itself. Although roll pass design for section rolling is usually based on the empirical knowledge of human experts, most of the empirical formulae only give good results within a limited range of applications.

The 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.
