Optimization of Multiple Response Characteristics in the WEDM Process of Buderus 2379 ISO-B Tool Steel Using Taguchi-Grey-Fuzzy Logic Method

Abstract:

In this study, the optimization of cutting width (Kerf), material removal rate (MRR), surface roughness (SR) and recast layer (RL) in WEDM was investigated by using Taguchi-Grey-Fuzzy logic method. The experiments have been conducted under varying arc on time, on time, off time, open voltage and servo voltage. An orthogonal array, signal-to-noise (S/N) ratio, grey relational analysis, grey-fuzzy reasoning grade and analysis of variance were employed to study the performance characteristics in the WEDM process of Buderus 2379 ISO-B tool steel. Experimental results show that on time gives the highest contribution for reducing the total variation of the multiple responses, followed by off time, open voltage, servo voltage and arc on time. The optimum performance characteristics could be obtained by using the values of AN, ON, OFF, OV and SV of 1 A, 1 µs, 15 µs, 95 V and 55 V respectively.
