Abstract

In this study, optimization scheme for minimum machining force and amplitude during end milling of Al6061 reinforced with SiCp has been presented. The input parameters considered for the analysis are cutting speed, feed, depth of cut and weight fraction. Experiments are designed based on Taguchi L25 orthogonal array. The parametric influences on responses are discussed through main effects plot. Further, hybrid Grey Relational Analysis (GRA) and Principle Component Analysis (PCA) was performed. Results revealed that weight fraction is the considerably influencing factor affecting the responses followed by depth of cut, speed and feed. The optimum cutting parameters obtained are cutting speed 2500 rpm, feed rate 20 mm/rev, depth of cut 0.2 mm and weight fraction 4%.
