Comparative Evaluation for Studying the Parametric Influences on Quality of Electrode Using Taguchi Method Coupled with MOORA, DFA, and TOPSIS Method for Electrochemical Machining

Abstract

The selection of optimal parameters of electrochemical machining (ECM) processes plays a noteworthy part in optimizing the measures of process parameters. Hence, evaluation of material removal rate and surface roughness is of enormously important in ECM. Developed in this paper is the application of Taguchi-based MOORA technique, desirability function analysis, and TOPSIS method for optimizing the responses of chromoly steel with the help of hexagonal-shaped brass electrode and brine solution. Multi-objective optimization has been done to investigate the influence of process parameters, i.e., voltage, tool feed rate, and signal on MRR and surface roughness. Optimal factor setting obtained from each optimization technique was compared, and confirmation test was done to validate the results obtained from electrochemical machining.
