TEMPERATURE FIELD IN EDM OF CERAMICS COMPOSITES

Composite ceramics materials have known an increasing development, because of their important characteristics and advantages, so, among them, an important role is that of electro-conductive ceramics composites - E(c)CC(s)-Al(2)O(3)/TiC. In order to obtain a part with specified shape and dimensions, made of this material type, most of the times a massive electrode electrical discharge machining EDM - by shape copying is needed - EDM - S(m)C(o). This paper presents theoretical and experimental research on temperature distribution field, for the previously mentioned machining procedure, carried on in order to get a mathematical model of temperature distribution. The theoretical assumption has been validated by experimental results.
