Research on CNCbCAD&CAPP Technology in Intelligent Numerical Control

This paper is based on a new philosophy of CNC (computer numerical control), which is named as INC (Integrated Numerical Control or intelligent numerical control). CNCbCAD&CAPP (CNC technology based on CAD&CAPP) is one of the most important key technology used in INC. First this paper has a brief introduction of INC and describes the important characteristics of INC. Second it introduces and analyses the one of INC's three key technologies: CNC technology based on CAD&CAPP, which has mended general CNC system to fit CAD&CAPP. It mainly includes building a new INC standard with a STEP (standard for the exchange of product model data) extension, expression based features, embedded technology, real-time Linux technology and so on. It focuses on discussing the theory and the principle of them.
