Advanced developments in research open up new potentials

An increase in process stability, quality assurance, and an optimal process chain treatment in combination with high flexibility, are the goals of process development on Fraunhofer Institute IWU. The trend towards lightweight construction in automotive production has lead to the use of hollow shafts in vehicle gear boxes. High potential is expected in the development of forming processes with partial roll-off tools. The publication focuses on the theoretical and experimental aspects of combining cross rolling and spin extrusion in accordance with the specific requirements of the car industry. These rolling technologies provide new opportunities to design effective and compact manufacturing sequences and simultaneously improve the quality of the manufactured parts. An approach to experimental methods for the determination of local forming parameters and several simulation methods are outlined.
