Abstract: A View-Function-Component (VFC) modeling methodology oriented to Computer Numerical Control(CNC)system domain was proposed, which captured general domain features from multi-view and then mapped to corresponding multi-view container. The domain meta-model was constructed in the container according to the features. Based on the language, hierarchical architecture modeling, dynamic behavior modeling as well as hardware platform modeling were conducted in corresponding architecture view, behavior view and system view. Formal performance verification of the CNC system could be realized through the application model simulation in early design stage. Based on this, automatic generation of object-platform-oriented codes was realized by code generation interpreter. By applied in two CNC systems of two axis lathe and three axis milling machine, the effectiveness of the proposed method was verified.
