| 摘 要： | 在分析国内外关于自由曲面数控加工中刀位点轨迹生成算法的基础上，提出了一个关于刀触点轨迹连续性的命题并加以证明，对各种形式的刀具与工件的几何特性进行了分析，阐述了该性质在改进刀位点轨迹算法中的应用方法，通过在“最小有向距离算法”中应用表明，该性质对于提高计算速度和精度方面都具有重要意义。

| Abstract: | Based on analysis of generation algorithms of cutter - contact point trace in NC machining of sculptured surfaces, in this paper, a property on continuity of cutter - contact point trace is suggested and proved. By analyses of geometry characteristies of various cutters and workpieces, the methed of application of the property to improving the algorithm on calculating the cutter - contact point trace is presented. It is also pointed that the property is very important for improving calculating speed and quality by using in “the algorithm of seeking minimal orientationdistance”. |
