一、前言当前,电火花加工机床的发展是显著的,过去仅仅用来加工模具的电火花加工机床,现在也被用到成品加工的领域。随着经济的发展,工业产品要求多样化和降低成本,因此需要缩短模具和成品加工的周期。在这方面,由于电火花加工工艺所具有的共知的优点,而获得了种种应用。 I. Introduction At present, the development of EDM machine tools is remarkable. In the past only the EDM machine tools used to process molds were used in the field of finished products. With the economic development, industrial products require diversification and cost reduction, so the cycle of mold and finished product processing needs to be shortened. In this respect, various applications have been obtained due to the well-known advantages of EDM processes.
