Abstract: For the question of difficult to control discharge process between the electrodes in WEDM, Systematic analysis of the relationship breakdown and the distance between poles、the relationship of the breakdown voltage and pulse duration、the relationship breakdown and impurity、the relationship breakdown and the temperature、Summed up the WEDM in the general laws of the electrode gap breakdown、So as to better control of WEDM process in the very room provides a theoretical basis for discharge.

Abstract: Electrical explosion of wire has a prosperous future in fine powder producing. In the process of electrical explosion of segmented metal wire (EESW),energy deposited in the wire was influenced by process variables such as the initial charging voltage of the capacitors, the length and the diameter of the segmented wire,and the electrode spacing. For understanding their relation completely, a series of experiments of electrical explosion was carried out with variations of the initial charging voltage and the segmented wire lengths and diameter. Results show that, energy deposition efficiency was weakly dependent on the wire length , whereas it has a strong dependence on the wire diameter, the initial charging voltage of the capacitors have an important influence on the energy deposition.
