Abstract The article is devoted to the experimental evaluation of the effect of EDM modifying the original smooth surface of the wire tool on its technological parameters when cutting different sheet materials, in particular, on cutting ability, surface quality of cut and quality of cut complex contours with sharp change of direction. It is shown that as a result of modifying the surface of the wire, single holes are formed on it that do not overlap each other, having metal flows on the edges that go beyond its original contour, which give it cutting ability. It was found that with an increase in the modification process, the energy of the electric discharge and the number of holes formed on the surface of the wire, its cutting capacity increases. It was established that when using the test wire tool, a clearly defined waviness is formed on the cutting surface, the appearance of which is due to the low rigidity of the tool, as well as the implementation of the process of destruction of the material both during its working and at idle. It is shown that the use of a wire tool with a modified surface makes it possible to ensure high quality and accuracy of cutting out of sheet materials with complex contour, characterized by a sharp change in the direction of its elements.
