ABSTRACT
The hollow embossing rolling of thin-walled high precision components like metallic bipolar half plates is characterized by narrow process windows. Here, the knowledge of interaction between forming machine, roll and process is crucial for the process stability and quality of formed bipolar half plates. In this paper, the elastic machine and forming roll behavior as a major influence parameter is described and analyzed on qualitative level and verified by simulation. This investigation involves a review regarding the process sequence, forces for the hollow embossing rolling of metallic bipolar half plates. By varying the load distributions, the elastic deformations of the forming machine and their forming roll are investigated and analyzed regarding process influence and potential for process monitoring.
