Computer Numerical Control (CNC) turning of AISI 1060 (High carbon steel) has been carried out to analyze the effect of various process parameters (cutting speed, feed rate, depth of cut) on surface roughness. Taguchi's L9 experiments have been carried out. Carbide inserts of IC807 grade PVD (Physical Vapor Deposition) coated have been used to turn the components. Results obtained have been analyzed using MINITAB software to calculate SN ratio with smaller the better criteria. It has been observed that feed rate is the major influencing parameter on surface roughness followed by cutting speed and depth of cut under experimental conditions. Also, surface roughness decreases with decrease in feed rate and increase in both cutting speed and depth of cut.
