Optimization of electric discharge machining process parameters on AA6351-Al2O3 composites

Abstract Electrical discharge machining (EDM) erstwhile considered as significant method for machining hard to-machine materials specifically metal matrix composites. In this research work an effort has been conducted to examine the effect of electric discharge machining process parameters Current (I), Pulse On Time (TON) and Voltage (V) on metal removal rate (MRR) and surface roughness (SR) of AA6351-10 wt%.Al2O3 composites produced through stir casting technique. Taguchi L9 orthogonal array was utilized to attain optimum parameters. From the examination it has been exposed that current is the foremost noteworthy parameter that distresses the MRR and SR.
