Abstract
The Aluminum alloy AA6061-4 wt% boron carbide (B4C) composites were fabricated by stir casting. The diesinker Electric Discharge Machining (EDM) was performed to create rectangular channels on fabricated AA6061-B4C composite. The Taguchi experimental design (L-9) with current (I), pulse-on (T-On) and pulse-off (T-Off) time as input parameters. The Material Removal Rate (MRR) and Average Recast Layer Thickness (ARLT) were considered as responses. The ARLT and surface topography of the machined zone were analyzed from the SEM micrographs. The regression model was developed and ANOVA was performed. Results that the current and T-On are significant parameters affecting the MRR and ARLT respectively.
