Optimalization of technological parameters of flow forming process

Abstract

The extreme price escalations of raw materials, energies and human labor lead to a progressive tendency to find new and more effective methods. One of this progressive method is the spin extrusion (Neugebauer et al. 2002, Neugebauer et al. 2001). An alternative use of the experimental spin extrusion machine is for flow forming. The aim of this work was in the first step to try to apply the flow forming on the forming of a thin walled semi product and verify the relevancy of this method. The second step was to try to find suitable technological parameters for the hollow shaft.
