During this work, the effects of various machining parameters such as feed rate,cutting speed, and depth of cut on surface roughness were experimentally observed during dry turning process. Aluminium 6061 alloy is machined using CNMG 120408 EN-TM (H20TI) CNC turning inserts. Response Surface Methodology (RSM) is used to design the experiment, to get regression equation and for optimization of the input parameters. Surface plots and Contour plots were generated by using RSM to check the interaction of input parameters on the surface roughness of the component. From the analysis of the experimental result it found that feed rate has maximum effect on surface roughness and cutting speed and depth of cut has minimum effect on surface roughness. The range of machining parameters are 0.1-0.2 mm/rev,124-207 m/min, and 0.05-0.8 mm for feed rate, cutting speed and depth of cut respectively. Best values of parameters are0.1 mm/rev, 165.5m/min and 0.85mm for feed rate,cutting speed and depth of cut respectively.
