The cutting characteristics of newly proposed PVD coated tools by UBMS (Unbalanced Magnetron Sputtering) method are investigated. Dry side milling tests of austenitic stainless steel (AISI 304) and Ti-6Al-4V alloy (ASTM B348) are carried out with five kinds of coated tools: two UBMS coated tools and three commonly used AIP (Arc Ion Plating) coated ones. The UBMS coated films, especially UBMS-TiCN have smoother surface without droplets and lower friction coefficient than those of any other AIP coated tools studied. The lubricating ability of the UBMS-TiCN film reduces the cutting force, cutting temperature and adhesion of chips, so that long tool life and good finished surface are obtained. (C) 2012 CIRP.
