Research on CAPP Technology Oriented to CNC

摘要

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). CAPPoCNC (CAPP oriented to CNC) is an important technology of INC. First the paper has a brief introduction of INC and describes important characteristics of INC. Second it focuses on introducing and analyzing one of three key technologies of INC: CAPP technology oriented to CNC, which has mended and advanced general process planning functions to facilitate manufacturing process. It mainly includes nesting optimization, motion expression based on characteristics, interactive CAD&APP technology and fuzzy information expression and evaluation. It also discusses the principle and application of them further. Finally, a case is given to illustrate how to realize CAPP technology oriented to CNC of a narrow-sense INC in engineering area
