Point-Based CAD/CAM Geometric Model Design

At present, CAD/CAM technology is applied in many areas, and machinery manufacturing was one of these areas in which CAD/CAM technology is the first and most widely used. With the development of CAD/CAM technology, CAD/CAM technology has become a key technology to improve the design and manufacturing standards, and enhance the competitiveness of the industry. In this paper, the concept of point-based geometric models used in CAD/CAM is proposed, the definition of the point-based geometric model and its CAD/CAM application process are suggested, and the geometric characteristics of the point-based geometric model and the CAD/CAM system development methodology are analysed.
