Application and execution of CNCbCAD&CAPP technology in INC

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 techniques 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 establishing 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 application and execution of them further. Finally, a case in Linux platform is given to illustrate how to realize CNC based on CAD&CAPP in engineering area.
