CAx Process Chain for Two Robots Based Incremental Sheet Metal Forming

Robot based incremental sheet metal forming, also called Roboforming, is a dieless incremental forming process. It is especially suitable for rapid prototyping and manufacture of small batch sizes with low costs. This paper introduces the whole process Chain of this method, including CAD, CAM and CAE. With the use of this process chain, not only the robot programs for forming experiments, but also the simulation results of formed workpieces can be obtained. Furthermore, the CAE-results are used in the CAM-process to realize the tool path planning considering both CAD-models and many real influencing factors on the forming accuracy.
