Abstract


The importance of Electrical Discharge Machining process is increasing, especially for the machining of electric conductive ceramic materials. EDM is particularly ideal due of its thermal operating principle, which allows for almost force-free machining. The effect of air on the machining characteristics of the dry electrical discharge machining (EDM) process is investigated in this study. Researchers regard dry electrical discharge machining to be an environmentally benign machining process, and many elements of this machining method are discussed in the specialized literature. The liquid dielectric is replaced by a gaseous dielectric in dry electrical discharge machining, which is a variation of the oil EDM method. The study describes a reasonably simple gadget that can be used to drill with dry electrical discharge. Dry EDM has a significantly lower material removal rate (MRR) than wet EDM. The impacts of various parameters on MRR were compared in the case of dry EDM. The thickness of the workpiece and the work material had a significant impact on the MRR.
