摘要：
The present work deals with the optimization of material and machining parameters for surface finish and Material Removal Rate (MRR) enhancements while turning Aluminium/Rock dust composite through Taguchi and Grey Relational Analysis (GRA). Rock dust particles weight percent (5, 10 & 15%) and particle size (10, 20 & 30 mu m) are varied accordingly to investigate the effect of reinforcement parameters on composite properties. Along with reinforcement weight % and particle size, also the turning parameters viz. speed, feed and depth of cut are chosen as input parameters with surface roughness (R-a) and MRR as responses. CNC turning is performed based on the L27 orthogonal array designed by Taguchi approach. Results expose that feed has remarkable effect on Ra and MRR rather than any of the other parameters examined. The optimum parameter combination identified through Multi criteria optimization technique GRA is S2W2N3F1D3 and the improvement in GRG approximates to 0.194. (C) 2020 Elsevier Ltd.
