Cutting characteristics of PVD-coated tools deposited by Unbalanced Magnetron Sputtering method

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...

Zusammenfassung: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.
