Abstract
The new type of electrical discharge machining without immersion of the processed workpiece is characterized by higher cost-effectiveness, simplified maintenance, and safety. In addition, a molybdenum wire with multiple reversible feed is used as a cutting tool, instead of a consumable brass wire. This study presents the results of experiments on processing tungsten single crystals by varying the technological modes of electrical discharge cutting. The dependences of the effect of the duration of electrical discharge pulses and the pause between them on surface morphology, depth of interplane crack formation, and cutting speed were determined. Molybdenum wire with a diameter of 0.18 mm and a tungsten single crystal with a thickness of 15 mm were used as tools and working material in the experiments.
Keywords: tungsten single crystal, electrical discharge cutting, damaged layer, interplane cracks
