Abstract

This paper deals with improvisation of electrical parameters which are necessary for working of micro-electrical discharge machining (micro-EDM/μ-EDM). TOPSIS formulation was used for the evaluation purpose. The advancement of electrical parameters was done to increase the material removal rate (MRR) and understate the tool wear rate (TWR) and overcut (OC). A prototype has been built up to carry out the investigations. Being difficult to cut material, Ti–6Al–4V was used for the assessment. The experiments were conducted by the design of experiments through Taguchi’s orthogonal array with three electrical factors, viz., peak current (Ip), pulse on time (Ton), and duty factor (DF) at three levels. The results were analyzed by TOPSIS method. It leads to better results than other optimization methods. Finally, ANOVA test was performed to accomplish the contributions of the working parameters toward the quality characteristics.
