Abstract

In the case of the electrical discharge machining, the obtained surface is a concatenation of craters generated by the electrical discharges. The dimensions of the crater generated by a single electrical discharge could offer an image concerning the material behavior during the electrical discharge machining and the phenomena corresponding to this machining technique. To ensure better conditions for the experiments development, a research schema based on the initiation of the single electrical discharge between the rectilinear edges of two parallelipiedic bars placed in plans perpendicular each other was applied. A factorial experiment with two independent variables at two levels was used to establish an empirical relation type power; the relation emphasizes the influence exerted by the voltage and by the capacity of the relaxation circuit on the dimensions of the crater. The sizes of the exponents proves the bigger influence exerted by the input factors on the crater width.
