摘　　要：针对电火花线切割加工(WEDM)开放式数控系统对解释器的要求,采用了以RS274解释器为基础,结合WEDM的工艺及运动特点,设计并实现支持WEDM加工C代码指令,双平面运动G代码指令及其他辅助加工M代码指令的解释器。最后给出了运行实例,验证了该方法的可行性与正确性。A new interpreter was developed for wire-EDM CNC base on an open source interpreter known as RS274.RS274 was used in traditional open-architecture CNC system,which was not compatible with wire-EDM CNC systems.Based on wireEDM characteristics,especially the characteristics of process and motion,the implemented interpreter can interpret NC codes such as C-codes for process control parameters and G-codes for servo motion.Besides the straight traverse motion of the Z-axis,for skewcurve machining,the servo motion requires a coordinated movement between the wire and the workpiece on the XY-plane and the UV-plane.In addition,practical examples are discussed,the feasibility of the method was proved.
