摘　　要：针对平面二次包络蜗轮的数字化建模与数控加工问题,提出对蜗轮理论齿面运用截面法沿接触线进行离散,将蜗轮齿面离散成型值点云,为运用三角B—B曲面片对蜗轮齿面进行插值重构提供基础。这一算法简化了复杂共轭齿面的计算,提供了适于计算机表达的数据接口。To establishing a precise numerical model of this kind of worm gear, which is the base of CNC manufacturing, the theoretical tooth surface is represented by a series contacting points which can be interpolated by B-B triangle pitches to rebuild the tooth surface.
