Tool wear and workpiece overcut have been studied in electrical discharge machining process with rotational external magnetic\r\nfield and rotational electrode. Experiments have been divided to three main regimes, namely, low-energy regime, middle-energy\r\nregime, and high-energy regime. The influence of process parameters were investigated on electrode wear rate and overcut. Results\r\nindicate that applying a magnetic field around the machining gap increases the electrode wear rate and overcut. Also, rotation of\r\nthe tool has negative effect on overcut.
