Optimization of Turning Parameters with Carbide Tool for Surface Roughness Analysis

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 in the free cutting steel for bulk applications for joining elements in mechanical engineering and automotive components. The experimentation was carried out using three variables namely cutting speed, feed rate and depth of cut. The main objective of this work is to find out the optimal cutting parameters that affect the surface roughness values Ra and Rz. Tool used for the study was Taguchi analysis. The optimized values for surface roughness Ra and Rz were obtained and found out that the effect of feed rate is the most significant factor on the surface roughness of the work piece.
