| Abstract: | In this paper, the machinability behavior of hybrid metal matrix composites (HMMCs) has been experimentally investigated. The experiments were performed at different level of (i) discharge current, (ii) pulse-on-time, (iii) pulse-off-time, and (iv) tool rotational speed. The intrinsic influence of these parameters on the material removal rate (MRR) has been investigated during electrical-discharge drilling (EDD) of developed HMMCs using copper electrode and quenched copper electrode. The influence of powder-mixed dielectric on MRR has also been investigated. The results of the experimental investigation indicated that the MRR is increased with discharge current (6 to 30 A) and pulse-on-time (60 to 500 µs) and decreased with pulse-off-time (8 to 90 µs) and tool rotational speed (400 to 1200 RPM). |
