Abstract: Finding ways of precise machining and cutting circonstances such as the hardness of metal machining, leads us straight to the use of unconventional methods such as electric discharge machining, electrolytic machining, laser machining etc. In fact, the machining of molds for plastic injection, aluminum injection still requires an extreme precision and a best possible surface for the extraction of parts produced without possible deformation or fixing. Technically, electroerosion allows a greater precision and possible unequaled details with other processes. The aim of this study is to familiarize the manufacturer with this machining process by studying the interactions discharge parameters and their influence on the surface finish and the volume of chips debited to electroerosion. The results are given in the form of curves, which will enable us to choose the optimal regimes for pulse generators encountered in the workshop. But, the process has some major disadvantages that must be taken into consideration in order to carry out the machining operations in good conditions.
