Development and Performance Optimization of Ecm Parameters on Scrapped Alloy Wheel Metal Matrix Composites

Abstract

Electrochemical machining (ECM) is a nontraditional technique for application of metal matrix composites in aerospace, military, and other engineering uses. ECM factors such as voltage, electrolyte concentration, duty cycle, and electrolyte temperature are varied to evaluate the machining rate. radial overcut, and delamination factor on scrapped alloy wheel MMC. The entropy-based weight assessment method coupled with gray relational analysis is used to perform multi objective optimization. As per the entropy method the weight assigned to MR, ROC and DF is 0.3105, 0.3432 and 0.3463, respectively. The gray relational grade predicts that 8 V, 20 g/lit, 50% and 40°C is the optimal setting for higher machining rate and lower radial overcut and delamination factor.
