M Micro-EDM (Micro Eletrical Discharge Machining) is the development of EDM machines. This study aims to make the accuracy of the excavation process with a micro-EDM machine equipped with rotating electrode. The difficulty of machining with micro-EDM is that there is often a short circuit between the electrode and the workpiece. For this reason the study was carried out with rotating electrodes in the hope of minimizie short circuit. However, the mechanical results of the electrode rotate at deviation or deflection at the end of the electrode. The effect of this deviation can cause decency in the drilling process. It is expected that the accuracy data obtained can complement the characteristics of the micro-EDM engine developed.
