This paper documents the development of a novel CNC metal forming process called “Stretch roll forming”. It is an extension of the three roll forming (or slip-roll) process, wherein many pairs of roller-like dies mounted on positioning slides are used to approximate the instantaneous geometry of the part being formed, and to guide the formation of extrusions and sheets into desired shapes. ...Parts with constant radius as well as variable radius along the length have been formed. This CNC metal forming process eliminates heat treatment and produces higher quality parts while eliminating the need to use part specific dies for a wide class of parts.
