Work is devoted to the process of wire- EDM machining engraved. In this paper, the actual problem associated with the calculation of magnitude of deflection electrode wire during the cutting process. Due to the complexity of the physical processing associated with the random nature of the breakdown between the interacting surfaces, resulting in cutting parts flexible electrode - wire may cause breakdowns, aimed not at the cutting plane. This gives rise to a force applied to the wire stretched in the direction perpendicular to the cutting direction, whereby the wire is stretched in the transverse parasitic oscillations arise, leading to impaired surface flatness of the side cutting, the appearance of the geometric dimensions and deviations of the profile of the cut. During the obtained equation allows to calculate the amount of deflection of the wire. Calculated the magnitude of deflection of the wire in the processing of titanium billet. The basic factors influencing the amount of deflection electrode - wire during electrical discharge machining process.
