Aluminum-based metal matrix composites offer a wide range of uses in biomedical applications. In this present study, a detailed examination is done to ascertain the impact of process parameters of electrical discharge machining (EDM) such as current (I), pulse on time (Ton), and voltage (V) during machining of boron carbide (B4C)-reinforced aluminum AA(6351) composite. The output characteristics such as surface roughness (SR), overcut (OC), and material removal rate (MRR) are investigated after the EDM process on the work material. The experimental results show that if the I and Ton are increased, a poor surface finish is achieved. OC is increased eventually for all of the improvement in the process parameters. In the case of MRR, it increases if I and V are increased. However, a negative trend is observed while increasing Ton. Finally, the machined surface characteristics reported the craters and lay formation.
