基于宏程序的变节距异形螺纹数控车削加工设计

Research on the NC Turning of the Variable-pitch Special-shaped Screw Based on the Macro Program

文章采用逐次分层拟合法数控加工原理,结合宏程序及其嵌套编制了变节距椭圆异形螺纹的加工程序,并经实践得以验证,该编程方法对其它异形螺纹件的数控加工具有借鉴意义。

In combination with the principle of successive hierarchical fitting NC processing as well as the macro program and its nesting,this article attempts to compose the processing program for the variable-pitch elliptical-shaped screw.The practice proves that this programming method is of great reference significance to the NC processing of the screws of other shapes.
