2016-6-27  The discharge voltage depends on the paired electrode materials and machining conditions. It ranges between 15 and 30 V. For proper machining conditions, electrical discharge occurs instantaneously and is independent from other electrical pulse parameters. Therefore, the most important electrical pulse parameters of EDM are discharge current and discharge duration. However, the impact of discharge current is limited by the tool surface which is interfacing the workpiece, i.e. the current density [22,23]. In case when the current density oversteps the limit for the given machining conditions, the process of deionization of the discharge zone deteriorates, thus reducing the efficiency of EDM. The independent regulation of the discharge duration is also limited. It is known from experience that discharge duration must be limited for a particular discharge current. Otherwise, an electrical
