摘　　要：实际加工中,一般采用步进电动机细分控制加工平台的运行,在垂直和水平两个方向采用逐点比较法插补运算逼近曲线。对于一些不规则图形,可先对加工指令表达的平面图形进行坐标旋转变换。介绍一种在线切割机加工过程中实现平面图形的任意角度旋转的方法。The stepping motor to control the machining platform operation were used. The interpolation by point - bypoint comparison was adopted in both horizoutall and vertical directions to yield an approximate curve. As for the irregular figures, the coordinates of the figures corresponding to the instructions were first transformed. A method for the random angly rotation of plane figures in the operation of electrical discharge wire - cutting machine was discussed.
