Abstract

In this paper, some preliminary experimental investigations have been reported for analysing the machining performance characteristics viz. Material Removal Rate (MRR) & Tool Wear Rate (TWR). Electrical Discharge Machining (EDM) of Inconel-718 alloy via helical threaded cryogenically treated rotary copper tool electrode is conducted. Impact of machining factors viz. peak current (Ip), pulse-on time (Ton), tool rotation (Nt) & hole depth (h) were investigated using Taguchi’s L9 (34) Orthogonal Array (OA). Optimum arrangements of factors for greatest MRR & least TWR were found in current study. Results predicts that Ip & Nt are two most affecting machining factors that affects MRR. Whereas Ip & Ton are two most affecting machining factors that affects TWR.
