Abstract: The micro-EDM process is one of the basic technologies capable of producing miniature, complex and three-dimensional features down to five micrometres size. As of today, the efforts of modelling the micro-EDM process are extremely limited, although its applications have been identified. As micro-EDM is a variant of the EDM process, and both are spark erosion processes in principle, an understanding of EDM process modelling is essential for the future modelling of the micro-EDM process. This paper presents an extensive review of modelling efforts in the field of EDM processes and proposes directions for the modelling of the micro-EDM process.

Keywords: anode erosion; cathode erosion; electro-discharge machining; EDM modelling; electrical discharge machining; micro-EDM; micromachining; non-conventional machining; plasma; single spark model; non-traditional machining; advanced machining.
