This paper presents the results of experimental work in dry turning of martensitic stainless steels (AISI410) using physical vapor deposition (PVD) coated carbide tools. The turning tests were conducted at different cutting speeds (110, 160 and 210 m/min); feed (0.1, 0.2 and 0.3 mm/rev) and depth of cut (0.7, 1.4 and 2.1 mm) respectively. The cutting tool used was B-TiC coated carbides. The influences of cutting speed, cutting tool coating and work piece material were investigated on the machined surface roughness (SR) and the Tool wear (TW). The results showed that feed significantly affected the machined surface roughness and depth of cut significantly affected the tool wear. The machining parameters which are affecting the quality of turning operation, it is necessary to optimize the machining parameters to obtain better productivity. Multi response optimization of machining parameters was performed with coated tool using grey relational analysis.
