摘　　要：宏观力小、可控性好、加工质量高是电火花加工的显著优点,特别是能加工各种复杂表面工具和高硬度、特殊性能的材料。因此,电加工在模具等精密零件加工中得到广泛应用。但是,模具精度要求越来越高,对应的加工设备性能指标要求也越来越苛刻。因此提高电火花线切割加工精度面临十分迫切的需求,这其中主要涉及到电火花放点过程、电火花加工机理、电火花加工工艺参数优化关键理论,这些都是目前国内外研究的热点问题。EDM electrode and the workpiece with macroscopic force is small,good controllability,etc.,so that it can process a variety of special properties of materials and a variety of complex surface of the workpiece, such as precision machining parts in the mold has been widely used. However, more and more high precision molds, and the corresponding processing equipment requirements are also increasing. Thereby, increasing the accuracy of WEDM is a very pressing need, which mainly related to the spark discharge point process,EDM mechanism and optimization of process parameters. These are currently hot research issues.
