| Abstract: | 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. |
