説明
Micro EDM with electrostatic induction feeding method can stimulate minimum discharge energy per pulse. With this pulse generator, since there is no contact between the pulse power supply and the tool, the tool electrode can be rotated at very high speed and significantly improve the cooling of the tool electrode. However, since the feeding capacitance which is formed between the feeding electrode and tool electrode is extremely small, it is difficult to conduct rough machining. Therefore, controlled pulse train method is introduced to increase the discharge energy. With this method, discharge energy can be enlarged even if the machining is done with the same small capacitance. Results show that material removal rate (MRR) can be increased with the increase in pulse train duration and higher MRR and lower tool wear ratio (TWR) can be achieved compared to the conventional method.
