Abstract

The resource efficiency of production processes implies the exact application of energy and raw part material. Therefore, the simulation-based process design plays an important role in order to avoid cost intensive and time consuming experiments. An established calculation tool is the finite element method (FEM). For high accuracy in simulation results, exact knowledge of the process conditions in the interface between workpiece and forming die is required. Thus, a realistic description of the friction in the contact area between raw part and forming tools in the FE calculation of hot forging processes is important for the usability of the simulation results. In this research work the newly developed IFUM friction model is presented and its application is shown for the calculation of complex forging processes.
