In the automotive forging industry, parts made of aluminum alloys are used more often due to the favorable strength to mass relationship and their high ductility. A possibility for preform processes for long flat pieces is a multi-directional forging operation in partly closed dies. In a current project, a multi-directional forming operation with three main axial directions is analyzed using FEM simulations. During the forging process, every two of three directions are combined with the third forming direction deactivated. The simulations are evaluated and analyzed regarding the form filling, the formation of flash and the development of temperature and fiber orientation. It was shown that with some combinations it is possible to realize a successful forming operation with the advantage of decreasing the quota of flash in comparison to conventional pre-forming processes. The detected optimal combination will be verified in a real forging process.
