In the design of sheet metal components and associated tools the use of forming process simulation based on finite element method is state of the art. The modelling of the forming process, however, neglects fundamental influences of the forming machine. But today, the machine behaviour influencing the process can be described with simulation tools sufficiently. The article presented here describes the current state of simulation for forming machines in regard to static and dynamic influences on the forming process. Furthermore, two examples and a proposal for enhancing the model are given.
