Ni-base super alloys are widely used in several industrial sectors, like petrochemical and power generation due to their high performance in aggressive environments. Inconel625 is primarily a Ni–Cr–Mo alloy used in different applications for its strength, excellent fabric ability and outstanding corrosion resistance. Machining of super alloy has been found to be a challenging task it has attracted considerable research. So, it is essential to know the cutting parameters for effective machining of super alloys. The present work focuses on finding the optimal cutting parameters for turning Inconel625 to achieve minimum surface roughness (SR), tool wear (TW) and maximum material removal rate (MRR) in CNC turning under dry conditions using TiAlN coated cutting tool. Single response optimization is performed by Taguchi method and multi response optimization is performed by desirability function analysis.
