| 摘 要： | 提出了圆锥样条合成矢量插补及其数控加工C机能刀补算法。建立相对坐标系,基于相对坐标系中曲线始点差分值递推计算曲线坐标值,实现圆锥样条统一插补。构建矢量圆,利用矢量圆与圆锥样条的矢量合成构建圆锥曲线等距曲线,进而实现圆锥曲线等距曲线的矢量合成插补,控制刀位点进给。在此基础上,设计圆锥曲线数控加工衔接处尖角过渡的解决方法,实现圆锥样条数控加工C机能刀补。实验证明:算法鲁棒、有效,满足工程应用需要。

| Abstract: | A new vector synthesis interpolation and C-function cutter radius compensation algorithm for cone spline NC machining is proposed.The curve's coordinate value in reestablished relative coordinate system is figured out by recursive calculation of the difference value of the curve's start end,and uniform interpolation for cone spline is achieved.In order to obtain the equidistant curve of a conic which is the track of cutter location point,a normal vector circle is created.After that,the equidistant curve of ... |
