Effect of SiC Particle Incorporated Dielectric Medium on Electrical Discharge Machining Behavior of AA6061/B4Cp/SiCp AMCs

In this work, it was observed that using motor oil as the dielectric fluid when producing AA6061/SiCp/B4Cp hybrid composites provided wealth from waste. these studies, modifications in silicon carbide (SiC) concentration, electrode (copper and brass), current, pulse time, reinforcing weight percentage were tested. Surface roughness machined hardness are measured reported for each removed piece of material. The bridging effect particles raised material removal rate (MRR), while a thorough flush enhanced Ra value. On topography, carbon content left dark smudges. Machining performance is superior to copper electrode-processed specimens. MRR, TWR, all rise discharge current duration increase. Because there no remelted layer, with low machining surface had better finishes. parameters optimized TOPSIS approach, efficiency by utilizing engine concentration 4 gl−1. Moreover, during machining, like on time 36 seconds, Amps, also brass electrode.
