| 摘 要： | 分析了数控系统控制插补器的关键是速度转接控制与准确控制问题．在六坐标ＣＮＣ工具磨床设计中提出了用位置误差的比例控制实现速度转接与用跟随误差作为提前预报量实现终点位置控制的插件器。为使数控系统用整数运算，在进给率的使用上提出了采样周期数的进给率方式．为提高定位精度采用了８ｍｓ采样的粗插补与４ｍｓ采样的细插补．

| Abstract: | It is analyzed that the key in NC position control's interpolater is speed smooth transition and accuracy control. It is proposed that speed transition be realized by using proportional controlling of positional errors, and terminal positoinal control by forecasting with tracing errors The feed rate of sample cycle number is presented for NC systems using integer operation. |
