Abstract

Dry electrical discharge machining is the process, which employs gas as the dielectric medium instead of liquid. Low material removal rate (MRR) and poor stability are the two major research issues of this process. This paper aims to investigate the feasibility and capability of the dry EDM process through a set of experiments. Experiments were performed using electrodes of diameters 3 mm and 3 mm with peripheral slots to analyze the effect of control factors such as gap voltage, discharge current, pulse on-time and duty factor (electrical), spindle speed and gas pressure (non-electrical). Statistical analysis using ANOVA for MRR and oversize showed that discharge current (I) and pulse-on time (Ton) were the most influencing factors for a dry EDM using slotted electrodes.
