Abstract

The article is devoted to the experimental study of the feasibility of restoring the cutting ability of the cutting disc by electrical discharge machining its surface directly in the performance of sawing operation. The description of the methodology of experimental research, including methodology of the electrical discharge machining (EDM) cutting disc working surface at different circumferential speed of rotation and a methodology to assess its cutting ability in the subsequent sawing them to samples from textolite. Presented and analyzed the results of experimental studies, reflecting the impact of the district disk rotation speed when the EDM surface on the intensity of the subsequent sawing them a sample of the PCB. It was found that with increasing peripheral speed of disc rotation during the electric discharge machining its surface, the cutting tool capacity plummets. Based on the research parameters holes formed on the surface of the disk at a different peripheral speed of rotation given to explain the experimental dependences. The studies proved that the use of electrical discharge machining the working surface of the cutting disc in order to maintain its high cutting capacity directly in the cutting operation, when the circumferential speed of the disc is equal to the cutting speed, is ineffective.
