基于宏指令的曲面螺纹数控加工工艺探索

Based on Macro Instruction of NC Machining Process Thread Surface Exploration

在数控车削加工实践中螺纹加工工艺已非常成熟,现尝试在曲面回转体(球面、椭球面以及抛物面、双曲面等)内、外表面加工出螺纹,采用切线法和割线法进行试验,能有效地加工出凸、凹球面上的螺纹。曲面螺纹加工工艺可以应用于一些特殊的蜗杆加工中或者一些拓展应用领域。

In the numerical control tuming processing practice thread processing technology already very mature, now try to surface in axially symmetrical （sphere, ellipsoid and parabolic hypoid, ere） inside and outside surface processing a thread, the tangent method and the secant line rule test, can effectively work out convex, concave spherical thread in the. Surface thread processing technology can he used in some special worm processing or in some developing field.
