摘要：
In order to develop an independently developed micro-EDM machine that can produce industrial-grade precision micro components, with micro array holes structure, key features of micro-EDM were anslysed, then a micro-EDM device with multiple functions was developed, providing a new open CNC system based on a PMAC motion control card and an industry PC. Emphasis is placed on analyses of compositions and control schemes of a CNC table control system, wire electrode grinding control system, pulse power control system, working liquid control system, and software system. The resulting CNC system can be applied to a machine that provides high accuracy motion. It satisfies processing requirements for signal control and feedback of pulse power in micro-EDM. So it can realize EDM electrode manufacturing on line as well as micro array hole machining. This research plays an important role in the further development of micro-EDM technology. ©, 2015, Editorial Board of Journal of HEU. All right reserved.
