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 behaviour as a major influence parameter is described and analysed 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 analysed regarding process influence and potential for process monitoring.

Potential of tool clamping surfaces in forming machines for cognitive production

High reproducibility of forming processes along with high quality expectations of the resulting formed parts demand cognitive production systems. The prerequisite is process transparency, which can be improved by increased knowledge of interdependencies between forming tool and forming machine that affects the tool clamping interface behavior. Due to the arrangement as surfaces transmitting process forces, their closeness to the forming process, and yet machine inherent, tool clamping interface provide greater potential for intelligent monitoring. This paper presents a holistic analysis of the interdependencies at the tool clamping interface. Here, the elastic deflection behavior of the press table and slide with their related clamping surfaces, the frictional slip behavior between the interacting machine components and the used clamping devices are described on qualitative level and verified by simulative analysis. Based on the results, available sensor systems are assessed regarding the capability to monitor the identified phenomena inline.
