A trend in the evolution of manufacturing processes shows a tendency towards the reduction of the size of the machine tool in a manner proportional to the size of part. Emerging technologies such as micro EDM require process parameters that have been seldom explored in the literature, to perform tasks that require high precision and productivity. This article presents the development of a circuit for power supply and gap control for micro EDM. To test the circuit, the selection of process parameters that maximize removal rates was explored using a Taguchi experimental design. The experimental confi guration of the micro EDM process used 0.7 mm copper electrodes, controlled by a micro-controller based RC circuit.
