ABSTRACT
Conventional roll forming process is one of the most common sheet metal forming processes where the strip is deformed by rotating rolls mounted on successive stands to produce a large variety of profiles continuously at high production rates. This process can only produce profiles with constant cross sections. However, a lot of components used in the automobile, railway cars, ship construction, and building industries have variable cross sections (Kleiner 2003). Therefore; flexible roll forming has been developed recently to produce variable cross section profiles.
