Abstract
A new roll-based process and machine for three-dimensional bending of profiles with symmetrical and asymmetrical cross-sections have been developed. Compared to conventional processes like stretch bending, the advantage of the Torque Superposed Spatial (TSS) bending is the kinematic adjustment of the bending contour, leading to higher flexibility and cost efficiency, especially in small batch production. To define the spatial geometry of the workpiece, a torque is superposed to the bending moment. Results of the analytical and numerical investigations concerning the mechanics of deformation and the machine parameters of the new process are presented.
