This study aims at investigating the effect of cutting speed, feed rate and depth of cut on surface roughness, microstructure of machined part and tool wear in dry rough turning of Ni superalloy Inconel-718 using PVD coated (TiAlN + TiN) carbide tool inserts. Taguchi's method for optimization of machining parameters (vc = 40-60 m/min, f = 0.05-0.1 mm/rev and d = 0.25-0.5 mm) was used. A Finite Element (FE) model of the tool geometry was developed in order to understand the trends of deformation and shear stress induced due to mechanical loads during orthogonal machining. Regression equations versus the cutting parameters were obtained for surface finish and tool wear. Changes in microstructure were found to be negligible. The investigation suggested that for PVD coated (TiAlN + TiN) carbide tool inserts, cutting speed of 60 m/min, feed rate of 0.05 mm/rev and depth of cut of 0.5 mm were optimum for producing the best cutting results.
