Axial-Radial-Forming is used to obtain shaft collars for rods or hollow gearshafts, which are needed e.g. in automotive engineering. Currently the industrial implementation of this method fails because process limits are reached at an early stage. Based on continuous developments, the technological boundaries are now expanded clearly upward and increase the process reliability. The progress could be essentially achieved by an optimization of the material flow. This permitted, due to a clear reduction of the necessary heating temperatures, the use of lubricants, which led to an evident improvement of the tribological boundary conditions. An important device for the process development is given by the Finite Element Analysis (FEA). The improvement of the material flow could be anticipated based on two-dimensional calculations. Concerning the forecast of the operating forces, clear errors could be shown in experiments. Since the operating forces represent a substantial factor for the machine manufacturers, a 3D-model was developed and representative results were obtained. The outcome of the development was verified by manufacturing a real part.
