This paper proposes an integrated approach to the study of the process of wire- EDM machining engraved, is to examine not only the changes of the treated surface, but also changes in the structure of the electrode - tool in the processing of different treatment regimen. As the workpiece is selected steel grade according to GOST 14959-70 65G. Of the workpiece held on the wire and a wire EDM Electronica EcoCut at various cutting conditions. Modes were selected on the basis of a stable processing conditions of the material at the maximum, minimum and average allowable amperage. As a tool electrode has been selected brass wire diameter of 0.25 mm firms Hando. Measurement of surface finish conducted on profilometer Mahr Perthometer S2 according to GOST 2789-73. Found that an increase in the average current EI exposed to strong destructive factors, such as high temperature zone of sparking, and high energy pulses.
