Optimization of technological parameters of flow forming process

Abstract

The extreme price escalations of raw materials, energies a nd human labor lead to a progressive tendency to find new and more effective methods. One of this progressive met hod is the spin extrusion. An alternative use of the experimental spin extrusion machine [1, 2] 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.
