Abstract
Electrical discharge machining (EDM) has emerged as one of the most preferred options for high precision machining of very hard materials. Complex contours and intricate slots are produced in a variety of parts by this approach. Considerable research has been dedicated to several aspects of EDM. This work concentrated on analysis of the effect of EDM processes parameters on performance measures such as material removal rate (MRR), tool wear rate (TWR) and surface roughness. In the present study experiments were designed using response surface methodology. Moreover the analysis of variance was performed for MRR, TWR and surface roughness, along with the empirical models which shows the R2 value as 86.79%, 72.80% and 83.47% respectively.
