Modeling of Friction Phenomena in Extrusion Processes by Using a New Torsion-Friction Test

Abstract

During the extrusion processes very complex adhesion and friction effects between the die surface and the extruded material occur. If they can not be controlled, the process can not be controlled either. In the framework of this study, a recently developed experiment for the investigation of the frictional phenomena under extrusion conditions will be presented. Based on the so called Torsion-Tribo-Test, low and high pressure load cases are considered. The experimental layout, the evaluation method as well as some measurements will be presented.
