摘　　要：以封闭型腔零件为对象,探讨了其数控铣削时的走刀路线。给出了粗铣型腔时沿Z轴方向切入型腔的三种方法,同一平面内粗切型腔时的三种走刀路线及精切型腔侧壁轮廓时的圆弧切入、切出方式,最后介绍了规划型腔拐角处的走刀路线的方法。对于数控程序的编制具备一定的指导意义。Taking cavity parts as the object of study,the cutter path of NC milling is discussed in this paper. Three methods of cutting into the cavity along the Z axis in rough milling are discussed,as well as the three kinds of cutter paths in rough milling cavity in the same plane and the method of cutting-in and cutting-out along arc in fine milling sidewall profile. Finally,the cutter path at the corner of the cavity is introduced. This paper has some guiding significance for the preparation of numerical control program.
