Influence of Silicon Carbide Particle Addition in the Aluminium (Al6061) Composite on EDM Process Parameters

Author(s): S. Bharani Kumar and S. Arul

In this study, a new approach of investigation has been traced, by subsequently mixing the Al6061 (base material) with SiC particulate. The percentage (by Volume) chosen was 5%, 10% and 15% SiC, respectively. The casted specimen with appropriate proportion was analyzed by cutting the specimen as per the prescribed standard. Through the electric discharge machining the holes (10 mm diameter and 2 mm depth) were produced on the specimens by varying the different flushing rates 0.5, 0.6, 0.7, 0.8, 0.9 and 1 kg/cm2, respectively. To validate the process of mixing ratio of SiC particulate on the based material Al6061, the surface roughness (SR) and Material removal rate (MRR) values were investigated through L27 orthogonal array.
