Research on Sawing and Milling Features and NC Programming of Plastic Door and Window

摘要

In this paper, the structure of plastic door and window and the characteristics of sawing and milling machining PVC profile are introduced, and on the basis of analyzing the relationship between function and kerfs of the window parts, the feature model of machining window profile is constructed, hereby making the geometry modeling and defining the essential elements of design feature make the process of automatic NC code generation simplified and its reliability strengthened.
