Abstract
Production features of micromachining ceramic workpieces using electrical-discharge machining are studied. The effect of pulse duration, breakdown voltage, voltage gain factor, peak current strength, and working voltage for electrical-discharge machining of VOK71 ceramic workpieces on roughness at the bottom of a channel and electrode-tool end wear are established. A mechanism is proposed for surface formation with electrical-discharge machining of current-conducting ceramic and recommendations are formulated for improving micromachining efficiency for components of this material.
