Influences of contact pressure, sliding velocity, lubricant, bending angle and surface texture on friction behaviours in stainless steel strip drawing

Abstract

This article investigates the tribological effects of stainless steel strip drawing by considering the influences of contact pressure, sliding velocity, lubricant, bending angle and surface texture. The die and sheet materials used to carry out the strip drawing tests were SKD11 and AISI 304, respectively. Different values of the contact pressure, sliding velocity and bending angle were tested. Various types of lubricants and die surface textures were also investigated. The results show that there was an optimum value of friction coefficient for each condition. The minimum friction coefficient was found at the condition having 9.375 MPa contact pressure, 100 mm/min sliding velocity, chlorinated oil, 45º bending angle, and smooth coated die surface.
