Wear of Tools Coated with Various PVD Films: Correlation with Impact Test Results by Means of FEM Simulations

Abstract

Abstract The use of appropriate cutting conditions and coatings is an issue of pivotal significance since it affects the overall tool performance in manufacturing processes. This paper introduces a quick and innovative procedure for characterizing the coating cutting performance based on the film impact resistance. A correlation between coating impact resistance and cutting performance under various conditions is established. Depending on the coated tool and the workpiece parameters, there are concrete cutting speed and feed rate regions, which can be effectively detected considering the previously mentioned correlation, leading to an enhanced cutting performance. magnified image
