In the present research work, Al6063 aluminum alloy has been machined by powder mixed Electric discharge machining (PMEDM) process. The effect of various process parameters namely pulse on time, pulse off time and silicon powder concentration on the performance measures such as material removal rate (MRR), tool wear rate (TWR) and surface roughness (SR) has been investigated. The experiments were carried out as per design of experiments approach using L9 orthogonal array. It has been analyzed that the peak current and powder concentration have significant effect on MRR, TWR and SR. Moreover, it has also been concluded that the addition of silicon powder into the dielectric fluid of EDM resulted in an increase in MRR whereas TWR, SR has been decreased. The results from this study will be useful for manufacturing engineers to select appropriate PMEDM process parameters to machine Al6063 aluminum alloys.
