Abstract
The trend towards lightweight construction in vehicle manufacturing has resulted in an increased use of hollow shafts in vehicle gear boxes. In order to maintain their competitiveness, producers have to continually find ways to reduce their costs and improve the quality of their products. This publication focuses on near-net-shape and net-shape forming of rotation-symmetrical workpieces by incremental rolling processes. Two methods, cross rolling and spin extrusion, which can be used in combination or individually are described. In addition, other approaches of experimental methods for determination of local forming parameters and different simulation methods are included. The presented rolling technologies provide new opportunities to design effective and compact manufacturing sequences and simultaneously improve the quality of the manufactured parts.
