Three-roll-bending offers the advantage of a high flexibility of the producible contours and the applicable profile geometries by comparatively low tool costs. However, with the exception of some standard profiles, the bending of radii and contours is controlled manually. Therefore, the profile bending with the three-roll-bending machine requires high manpower and high competence of the operator. A continuous monitoring of the profiles is hard to be realized as well. In particular the variation of the profile characteristics requires a steady adaption of the process in order to assure a constant product quality.
To develop the adaptive feedback control, a numeric model of the process is set up, which is validated by an experimental study of the process. With the help of the conducted simulations, a process analysis is carried out, in order to determine suitable and measurably actuating and control variables. The developed feedback control will be tested in further simulations and after that implemented on a machine prototype and applied to the real process.
