Abstract: “In this study Taguchi approach was used, which provides the design with a systematic and efficient method for conducting experimentation . The experiments are designed using L9 orthogonal array considering three process parameter such as, Current, Pulse-On Time, Pulse-Off Time, the response of the process such as Material removal rate (MRR), Tool wear rate (TWR), Surface roughness (Ra) are considered. The experimental data used in this paper is based on the research work done by Raghuraman S et.al. The analysis of various performance criteria such as, MRR, TWR, Ra, using Taguchi method and has been done. The input-output relationship modeling has been done using Fuzzy Logic. The predicted results obtained from fuzzy logic are compared with the experimental result. Moreover the multi objective optimization has been performed using fuzzy logic”
