摘　　要：根据DIN3960渐开线花键的坐标值,用EXCEL函数功能计算出不同压力角下渐开线的极角和极半径,表示成AutoCAD极坐标并通过样条线工具绘制出渐开线,再用齿顶圆和齿根圆直径截取一段渐开线作为花键齿面,并用分度圆直径绘制出渐开线齿剖面,经镜像和裁剪便可绘制出渐开线齿形。采用AQ550的图形驱动方式通过定义加工类型、割丝半径、工件厚度等生成其线切割加工程序。The involute polar angle and the polar radius under the different pressure angles was calculated using the EXCEL function aiming at the bisic dimension of the DIN3960 involute spline. And the polar angle and the polar radius was represented into AutoCAD polar coordinate, the involute was drawn through the spline linear tool. And then, a section of the involute was intercepted with the diameters of the point circle and the root circle, used it as the tooth face of the spline. The involute tooth thickness was drawn using the diameter of the divided circle and the tooth-form was drawn through rotating, mirroring image and cutting. Its linear cut machining program was created by using AQ550 figure drive mode through defining the machining type, the radius of the cut silk and the thickness of the workpiece and so on.
