摘　　要：针对复杂曲面电火花加工,建立了虚拟电火花成形加工机床。该虚拟机床在运动部件之间建立约束关系,采用组件矩阵变换技术对主动部件的位姿矩阵进行变换;采用软件插补技术对加工路径进行插补运算,驱动虚拟坐标轴运动,并在电极与工件之间作交割运算,去除工件材料。利用它可以解决复杂曲面的加工难题,提高工作效率。In order to solve the problems of electric discharge machining （EDM） of the complex surface, a virtual sinker EDM machine is created. Constrain relations are set up between motion parts and the matrix transform technology is used to change the posture of the component in the model. Then the interpolate method is adopted to compute the motion paths and drive the motion axes. The intersection operations are made between the electrode and the work piece. The virtual sinker EDMmachine is used to solve the actual problems on EDM.
