Content
Electrical discharge machining (EDM) process is widely used unconventional machining process in manufacturing industry for machining high hardness materials and to make dies of complex cavities. In this work experiments are carried out during electric discharge machining of Titanium alloy (Ti-6Al-4 V). Taguchi L9 orthogonal array is used to conduct experiments. Process parameters, such as, peak current, pulse on time and pulse off time are chosen for this study. Whereas performance characteristics namely material removal rate (MRR), tool wear rate (TWR) and surface roughness (SR) are selected for this study. The significance of process parameters on performance characteristics is analyzed. The objective of present work is to find optimal combination of parameters that gives maximum MRR and minimum TWR and SR simultaneously. Taguchi-data envelopment analysis-based ranking method is used for above multi-response optimization.
