摘要
在 CNC 机床上编程铣、磨削加工封闭平面廓线时,必须选择刀具进入切削和退出切削的合理曲线,从而保证廓线上进退刀点处的几何形状。本文提出用高阶密合曲线来实现这一目的。
In Programming enclosed plane profile milling and gsinding on CNC machine tools,it is neces- sary to select rational curve of tool getting into and withdrawing from cutting so as to eusure geometrical shape of profile on points where tool advances and retreats.This paper puts forth the fitting curve of high order to fulfill this object.
