Abstract

The Al6061 alloy reinforced with SiC particle is proposed to be casted by stir casting technique; SiC with 36µ size will be used. Casting will be done by varying the percentage of SiC from 3%, 6% and 9% by weight and preparing the specimens. The wire electrical discharge machining has been used for machining characterization of Al6061/SiC composite. In this process, parameters are Pulse-on time (TON), Pulse-off time (TOFF), Current (I) and Bed speed (BS) will be varied to find their effects on Surface Roughness (Ra). The experiments were proposed to carry out as per design of experiments (DOE) according to the selected L9 orthogonal layout. The results obtained from this study are presumed to be applicable for manufacturing engineers to choose appropriate WEDM process parameters to machine MMCs of Al6061 reinforced with SiC at various proportions and Unfilled Aluminum.
