摘　　要：曲面类零件加工一直是数控加工中的难点,而刀触轨迹的生成又是其中的重点。本文基于B样条,利用Matlab写出了获得零件曲面方程的程序,采用一种改进型算法——自适应等参数线法生成刀触轨迹并利用Matlab模拟出了刀触轨迹。Surface accessory machining is always the difficulty in the NC machining and creates the correct cutting tools contact locus is the emphases in these surface accessory NC machining. This paper based on the B spline surface and make use of the Matlab to write the program that can gain the surface equation, adopt a improved arithmetic （self adapt equal parameter lines arithmetic） to produce the tools contact locus and make use of the Matlab to simulate it.

关 键 词：B样条曲面 自适应等参数线算法 刀触轨迹
