Results are presented from a study of the effect of the regimes used for electrical-discharge machining on the accuracy of small-diameter holes made in parts composed of high-density ceramics. It is established that increases in the breakdown voltage, voltage gain, peak current, and working voltage have different effects on changes in the diameter of the holes, their deviations from the prescribed shape, and the diameter and height of the cone at the bottom of the holes.
