The basic operation required for the preparation of various components in various manufacturing industries is turning and surface finish is very essential for the quality point of view. The surface finish of the components is an essential demand of the customer using components. Therefore to optimization of the surface finish is primary requirement so that the cost and the overall production will not be compromised. Thus in the research work the surface finish at various machining parameters is optimized. The rotation speed, feed rate and the depth of cut are considered as primary parameters affecting the surface finish. Some other factors affecting the surface finish are tool material, tool type and cutting fluids etc. The parameter influence most are cutting speed, depth of cut , feed, geometry of cutting tool like principle cutting edge angle ,rake angle, nose radius etc. For the optimization the surface finish it is very necessary to decide the controlling parameters. In the process of turning operation the different values of cutting parameters, cutting speed (165, 220,275,330), feed rate (.2, 0.3, 0.4, 0.5 mm/rev), depth of cut (.5, 1, 1.5, 2 mm) are selected. It is concluded that surface finish is highly influenced by speed than feed rate than depth of cut. Surface finish decreases with increase of speed. Surface finish is minimum at Minimum revolving speed. Surface finish is minimum at minimum depth of cut.
