This experimental study concentrates on the understanding of machining process in turning of 11sMn30 using carbide tip insert under dry condition.11SMn30 is an alloy of magnesium and zinc which is mainly used for cutting steel and act as a very good rotating element in mechanical engineering and automobile components. The experiment was carried out using three input parameters namely cutting speed, feed rate and depth of cut. The main objective of the current work is to find out the optimal cutting conditions that affect the surface roughness values Ra and Rz. Tool used for the study was Taguchi analysis. The optimum values for surface roughness Ra and Rz is found to be 1.854 and 12.899 respectively. Also it was found out that the feed rate is the most significant factor on the surface roughness of the work piece.
