Comparative analysis and modelling of newly developed and unconventional processesof plastic forming of toothed gear elements

J. Michalczyk, S. Wiewiórowska, Z. Muskalski
The article reports the results of a comparative analysis made for three novel unconventional gear wheel forging processes based on the authors' patented [5,6,21] plastic forming methods developed chiefly for the purposes of extruding hollow products as well as valves and pins. These processes are distinguished by the fact that part of the tooling elements which are normally fixed during conventional forging are purposefully set in motion. This is intended to change the conditions of friction
