Abstract
Expanding industry demand for machining of critical products from hard-to-machine materials and hard alloys makes the research aimed at finding optimal modes of electrical discharge machining topical. This is, for example, the determination of modes that provide the highest productivity or efficiency, or minimum tool wear, while ensuring the necessary roughness and accuracy of the product. In the present work, it is proposed to supplement the parameters monitored in electric discharge machining with non-electrical parameters, which include the parameters of vibroacoustic signals that accompany the working process. The paper shows that parallel recording of the discharge current vibration signals makes it possible to reveal the drawbacks of processing conditions and to influence purposefully the technological process modes in order to bring the processing conditions closer to the optimum ones.
