M.Ing. (Mechanical Engineering) / Micro electromechanical systems (MEMS) are presented and the application of electro discharge machining (EDM) to this scale of manufacture is discussed. A model relating input variables to output variables of micro scale EDM is developed using dimensionless groups and least squares regression. The model is used in a numeric simulation that ultimately predicts the space of a micro crater. Experimental validation is performed to check the reliability of the model by comparing the measurable experimental outputs with the outputs predicted by the model. The results and validity of the model are discussed.
