Experimental investigation of the effect of lubricant change on automotive component

Abstract Manufacturing problems resulting from lubricant supplier changes are relatively common in automotive press shops. Simulations using computer-aided design (process and tool) detect a significant proportion of manufacturing before tools physically produced. In modern forming codes, an enhanced Coulomb model is used to numerically the friction phenomena associated with lubrication. laboratory condition, determining parameters through physical measurement challenging. As result, it became necessary device that could be utilized industrial environments. this study, we present prediction problem change sheet metal part. The measuring has been developed based on materials. may determine pressure velocity dependent parameters. can only measure limited range pressures velocities, so results extended wider mathematical method. demonstrate effect material process AutoForm code.
