The objective of the study is to evaluate the effect of machining parameters on the Material Removal Rate and Surface Roughness in CNC Turning by implementing Taguchi technique. Based on the Taguchi method, turning experiments were designed and conducted on Nylon rods. CNC Turning is a machining process which is used for removing the unwanted material from the cylindrical surfaces of the workpiece. In this era of manufacturing, Material Removal Rate (MRR) and surface roughness qualities are of primary concern. Taguchi method has been employed with an L36 orthogonal array. Four cutting parameters namely cutting speed, feed, depth of cut and Insert Nose Radius is selected. Two different values are selected for insert nose radius and three values are selected for each of the other parameters. Turning operations are performed for maximum Material Removal Rate and minimum surface roughness response values. The material selected for machining is Nylon which is a thermoplastic material and the tools used for machining are of rigid Cast Iron with solid carbide inserts and AP68 servo oil is used as the coolant. Material Removal Rate is calculated for 36 experiments and surface roughness values are measured. Taguchi method in MINITAB software is used for optimization and the optimum values of the four parameters namely cutting speed, feed, depth of cut and insert nose radius to obtain a combination of higher material removal rate and lower surface roughness.
