Electrical Discharge Machining, EDM is one of non-conventional machining process that is currently applied for surface texturing. Power supply is one of the components in EDM that control process parameters which will directly influence the machining condition as well as Material Removal Rate (MRR). In this study, Flyback converter has been proposed as the new power supply. An experimental studies were conducted to verify the performance of Flyback converter by machining twenty micro-dimples in circular arrangement on metallic acetabular cup. Material removal are calculated by weighing the workpiece before and after machining. The results show a consistent value of material removal when Flyback converter is applied compared to Linear power supply. Therefore, Flyback converter is highly recommendation to be used as EDM power supply.
