- Abstract
The paper deals with the behavior of environmentally friendly dielectric liquids: rapeseed and sunflower oil, compared to an usual hydrocarbon based dielectric liquid. Experiments have been performed with these dielectric liquids, using them at classic electrical discharge machining (EDM) and ultrasonically aided electrical discharge machining (EDM+US). The results concerning productivity and the roughness of machined surface under these same working conditions were compared. Computerized models have been developed, using the finite element method for material removal mechanisms related to these processes. The aim was to explain the behavior of dielectric liquids under specific conditions of EDM and EDM+US.
