摘　　要：针对数控磨削的特点 ,提出了基于约束条件和成形过程的加工特种回转面刀具前、后刀面的刀位轨迹生成条件方程组。应用空间法向等距线及斜等距曲面原理对方程组进行了简化 ,提高了求解精度。Based on constraint conditions and forming procedures, equation groups of forming condition of machining special revolving tools are established in terms of characteristics of NC grinding. The equation groups can be used to generate tool paths for manufacturing rake and flank faces of the tools. The equation groups are simplified and the solution accuracy of equation groups is increased by using theories about the normal offset curve and inclined offset surface. The model is also suitable for different kinds of rotary shaped cutting tools.

关 键 词：特种回转面刀具 刀位轨迹 数控磨削
