N2 - An innovative forming process for the production of a functional component with internal and external gearing was developed at the Institute of forming Technology and Machines (IFUM) in the framework of the project A7 „dynamic Process Forces“ of the special research area TR73. The process is characterized by the new manufacturing technology sheet-bulk metal forming (SBMF). This technology combines a sheet- and bulk metal forming operation in which the semi-finished material is sheet metal. By combining these two technologies, the process limits can be extended. In order to reduce the friction between component and tool and to increase the surface quality of the component, superimposed oscillation is applied to the SBMF process. A hydraulically operated vibrating device was used to generate the oscillation overlay. For the identification of optimal oscillation parameters, ring compression tests have been carried out. The aim of these investigations was to analyze the influence of superimposed oscillation on the surface roughness as well as on friction characteristics. Therefore, frequency and amplitude of the oscillation superposition have been varied. In addition, the difference between lubricated and non-lubricated semi-finished materials has been analyzed. The surface roughness of the ring compression test samples was measured on a surface profilometer. The friction factors were calculated based on the geometrical parameters of the ring compression samples. The friction coefficients were also identified by numerical simulation. In addition, the influence of the oscillation parameters on the forming force was examined. The experimental results confirmed the initially assumed positive influence of oscillation.
