摘　　要：目前国内加工空间曲面零件通过采用锥度切割装置使电极丝倾斜一定角度来实现锥度切割,这种方法易产生的加工误差较大。论文在五轴联动数控线切割加工系统的运动分析的基础上,建立了直角坐标下空间曲面零件线切割加工成型的数控模型,阐述了利用G代码合成空间曲面的方法,提出了运用模块化技术设计空间曲面线切割五轴联动数控系统上位机软件设计方案,为空间曲面线切割CAD/CAM系统的研究提供了依据。Currently working space through the use of taper surface parts of the electrode wire cutting device tilted at an angle to achieve taper cutting, this method is prone to processing errors. In this paper axis CNC wire cutting system kinematics, based on the establishment of a Cartesian space forming surface parts CNC wire cutting model, elaborated space surface using the G code synthesis method. The proposed use of modular technology design space curved line cutting axis CNC system PC software design solutions for space curved line cutting CAD/CAM system provides the basis for research.
