This paper presents a model to calculate the trajectory correction electrode tool to obtain the desired accuracy in the processing of wire-EDM cutout. The mathematical modeling of the amount of correction tool-electrode is used the law of conservation of energy. Taken into account the physical nature of the process of electrical discharge machining materials. Based on the theoretical analysis data calculates the amount of heat required for heating, melting and evaporation of materials from the surface of the mass of the workpiece. Based on this model, the calculated value of trajectory correction electrode tool in the processing of the material 40Cr steel . The results of the study show that the amount of trajectory correction tool-electrode significantly affect the properties of the material, the height of harvesting and processing modes . Found that with increasing height substantially reduced processing performance value, the correction value increases. Increases in current leads to an increase correction. However, increasing the current increases the likelihood of breakage of the electrode – wire, thereby reducing the quality of the machined surface.
