Electrical discharge grinding (EDG) is a hybrid machining technique that integrates grinding and electrical discharge machining (EDM) by combining mechanical and thermal effects. By generating sparks between a non-abrasive spinning tool and the workpiece, this method works well for cutting materials with flat surfaces. The purpose of this study is to create an EDG setup and examine the effects of several input parameters, including current, wheel speed, pulse-duration, and pulse-interval, on the output parameters, particularly surface roughness (Ra) and material removal rate (MRR). A circular copper tool electrode was used in the studies on an Al-SiC-B4C-Mg hybrid composite workpiece. The results indicated that both MRR and Ra increased with higher currents, while Ra decreased with higher wheel speeds. Additionally, the effects of pulse-duration and pulse-interval on MRR and Ra were examined. It was observed that MRR increased up to a pulse interval of 45 μs but declined beyond this point. The study also includes a scanning electron micrograph analysis of the machined surfaces.
