Abstract

Electrical discharge machining (EDM) has found widespread applications in tool , mold and aerospace industries. Therefore, enhancement of the quality of the EDM process has become a major research concern. In this paper, the effect of various titanium powder concentrations on the Material Removal Rate (MRR), tool wear rate (TWR), surface roughness (Ra) in powder mixed electrical discharge machining (PMEDM) have been studied. The workpiece is SKD61steel and electrode made from copper with reverse polarity were used in experimental study. The results showed that titanium powder mixed into the dielectric fluid of EDM can enhance MRR without increasing TWR and Ra.
