Development of generic error correction functions for incremental forming based on feature detection and correction.

The proposed research entails a fundamental study of unwanted deformation phenomena and compensation strategies for incremental forming. Incremental forming is an emerging sheet metal working technique which has triggered a growing interest in recent years. The main advantage of this technique is the fact that, in contrast to more conventional forming techniques, no dies are required to manufacture a sculpted sheet metal workpiece. With this process, a flat sheet is formed into a 3D sculpted workpiece with basically only the aid of a CNC controlled spherical tool. The researchers are convinced that a promising, scientifically founded approach for increasing the accuracy of the SPIF process exists in the generation of refined toolpaths that are optimised taking the characteristics of geometric features of the workpiece into consideration. For this purpose the workpiece first needs to be segmented into different features by a geometric analysis module. Next, algorithms, to be developed, generate a toolpath with the aid of correction functions tailored to the detected features. Important input parameters for these algorithms are the material type, thickness, tool size, and maximum process time.
