Abstract
The paper presents the results of experimental research on the wear mechanism of the tool-electrode as a result of machining metal materials by applying electric discharges in pulse. It highlights the requirements that should be followed when designing and developing the tool- electrode. It examines several phenomena noticed on the tool-electrode surface, exactly, the oxide layer formation and the modification of the micro-geometry of the tungsten tool-electrode surface. The paper presents the experimental results on the behavior of the tool-electrode made of stainless steel after the metal parts have been machined. It also presents the phases of mass transfer in the gap between electrodes.
