Abstract: Owing to the non-isoenergetic nature of discharge pulses in resistance-capacitance (RC) based micro-EDM (μEDM), the volume of micro-crater generated by each pulse varies significantly. This fact has driven the researchers in this work to propose an electrothermal principle-based analytical model to approximate dimensional (diameter and depth) accuracies of such micro-craters. An investigation has been done to robustly apprehend the nature of energy distribution during single discharge micromachining in μEDM. The study gradually substantiates the theoretical nature of energy distribution during a single discharge. The predicted nature of energy distribution helps in comprehending the volume removed from the workpiece, energy loss, and machining efficiency.
