Abstract

On a Gleeble 3800 thermo-physical simulator, multi-axial forging of high-purity copper workpieces were performed. The strain rate during the simulation process was 0.1 s–1. The force response and the geometric changes of the workpiece as a function of time were continuously recorded. For a deeper understanding of the multi-axial forging process, a finite element model was created in Qform3D, analysing the changes in the deformation history. In the virtual model, tool movements were controlled using the recorded data of physical simulations. The force-displacement curves of the physical and finite element simulation were compared. The measured and simulated temperature and force values were used to ver-ify the finite element model.
