Abstract
The correct selection of production conditions is one of the most important aspects to take into consideration in processes related to the electrical discharge machining (EDM) of conductive ceramic materials, as it is these conditions that determine such important characteristics as surface roughness, material removal rate and the wear on the electrode. In the present work, a study has been made of the influence of the factors of the intensity supplied by the generator, the pulse time and the duty cycle on the given technological characteristics. The ceramic material used in the electrical discharge tests here was siliconized silicon carbide. This material is used in high-temperature gas turbines as well as in bearings, seals and furnaces. In this way, a series of mathematical models will be obtained using the technique of design of experiments (DOE) which makes it possible, by only performing a small number of experiments, to select the optimal machining conditions for finishing.
