Electrical erosion is widely used in industry for a long time yet, so that the call of "unconventional technology" is almost obsolete. The main obstacles to the widespread use of this technology consist in the relatively low yield of the process and the rapid tool wear. As a result, most researches in EDM are focused on improving the characteristics that can be obtained through this type of processing. This paper presents an alternative to the classic EDM, consisting of a process in which a
