The method of machining by impulse electric discharges in subexcitation regime (IEDSR) presents a machining method that allows obtaining some superficial layers whose properties differ from the properties of the basic material of the piece. This machining method has a lot of advantages compared to other machining methods such as, formation of the intermediate layer between the deposited layer and the base material, the lack of formation of micro cracks on the processed surface, possibility of using a wide variety of materials and so on. At the same time, the low productivity of the process, obtaining a surface with a high roughness, obtaining a non-homogeneous surface, make inefficient the using the given process. The paper below presents a description of the solution for layer deposition by IEDSR. The endowment of installation with a multi-electrode system that is powered by the generator of impulses and the use of two stepper motors that can execute up to 1800 micro-steps, controlled by a programmable microcontroller, successfully eliminates the disadvantages of the IEDSR machining process.
