Abstract | The current paper describes the multiple response optimization of electrochemical machining (ECM) responses, such asspecific energy consumption (SEC), overcut, and material removal rate (MRR), aimed at sustainable machining. Theexperimental work was conducted on electrochemical drilling of AA6061-TiB2 composite material. The concentration ofelectrolyte, applied voltage, and current were selected as the governing parameters in machining process. The Technique forOrder of Preference by Similarity to the Ideal Solution (TOPSIS) was applied to identify the optimal set of machining parametersbased on the closeness coefficient (CC). The weighting of responses was allotted by using the Analytical hierarchy process(AHP), or equal weights, or entropy method. The results indicate that the closeness coefficient varied by weighting. Acomparative analysis of the confirmation experiments showed that the optimal level of machining parameters obtained from theentropy weighting method gave the largest improvement in the closeness coefficient to attain sustainable machining. |
