Research on the Failure Analysis for Coating Cutters of PVD by the Finite Element

In order to study the failure cause of the wear and breakage of coating cutters, model of coating cutter is built by the Pro/ Engineer, and model file is imported into Ansys software so as to carry out the post-processing by the finite element, and subsequently mechanics, thermal and kinetic analysis of coating cutters are conducted. The failure reasons of coating cutters are also discussed which has certain reference value on the rapid development and to improve the durability for the coating tools.
