Rotary swaging enables the efficient production of rotationally symmetrical components with considerable material savings, making it ideal for future shaft production.

The rotary swaging process has so far been designed purely on the basis of experience, which makes it competitive almost exclusively for medium and large series. Preliminary investigations of the rotary feed angle – a process-describing variable in rotary swaging – revealed a dependency on component quality. The simulation of the rotary feed angle represents a challenge.

In this thesis, a numerical simulation is to be set up with an explicit solver in which the rotary feed angle can be observed. The results of the following parameter studies are compared with the simulation results of an implicit solver and validated on the real process.
