Experimental study and Analysis of Variance of Material Removal Rate in High Speed Turning of AISI 304L Alloy Steel

Material removal rate is one of the challenges encounters in the manufacturing process, due to the transformation of a raw solid material into desired shapes. This investigation involved studying the effects of the three variables (cutting speed, feed rate and depth of cut and their interaction) for material removal rate during turning of AISI 304L stainless steel with cemented carbide inserts cutting tool. Response surface methodology was employed in the experimental design and total number of 20 experiments runs were conducted using central composite design. The level of importance and performance characteristics of the machining parameters on MRR was determined by using analysis of variance (ANOVA). It was observed that the cutting speed had the most significant effects on the MRR (66.27%) followed by the depth of cut (21.55%), while feed rate (8.25%) had the least effect on MRR. The result also showed that the cutting speed and the depth of cut has good interactions during the turning operation. (paper)
