Optimization of Electro-Discharge Diamond Surface Grinding Process Parameters with Multiple Performance Characteristics of Ti-6Al-4V Using Grey-Taguchi Approach

Abstract:

The present paper reports the optimization of process parameters in hybrid machining process (Electro-Discharge Diamond Surface Grinding) of Ti-6Al-4V with multiple performance characteristics using the combination of Grey Relational Analysis (GRA) and Taguchi approach. The various input process parameters in this work are wheel speed (RPM), duty factor, current (ampere) and pulse on-time (µs). In this research work nine experiments have been conducted according to the Taguchi’s L₉ orthogonal array on in-house-designed & fabricated EDDSG set-up. The machining parameters wheel speed (S), duty factor (DF), current (I) and pulse on-time (T_on) are optimized with consideration of multiple performance characteristics such as material removal rate (MRR) and average surface roughness (R_a). The confirmation experimental results show that combined Grey-Taguchi approach enhances the machining performance in EDDSG of Ti-6Al-4V.
