The CAM system research of sawing and milling machining center for PVC profile based on feature technologies

By using the flexible sawing and milling machining center for plastic door and window PVC profile (SMMC) as an object, the paper approach for the basic frame, the main function and the key technology of the relevant CAD/CAM integrating system for the SMMC, and specify fully the feature technologies which are applied to the technical design for the SMMC. Through in-depth studying the geometric character, the technical character and the mutual relation between them which various windows shape on the structure and the machining figuration are possessed of. We gained the feature subclasses aggregate and the individual of the feature subclasses aggregate of the machining technological of windows shape. Consequently, such feature technologies in the flexible sawing and milling machining center for plastic door and window PVC profile system can greatly improve manufacturing efficiency and quality.
