Abstract

Higher material removal rate with better surface finish is one of the prime requirements of today’s industry. The present paper investigate the effects of cutting parameters like spindle speed, feed and depth of cut on surface finish and material removal rate of Aluminium 7075-T6. Taguchi methodology has been applied to optimize cutting parameters. Feed rate is the most significant factor influencing surface finish whereas material removal rate is significantly affected by cutting speed. For highest MRR with better surface finish. Cutting speed (15.102 m/min) ,feed rate (0.3207 mm/rev.) and depth of cut (0.5 mm) are cutting parameters for higher MRR and optimum surface roughness .
