Abstract: Methodology development of CNC system takes the field as a carrier centric model, which applies UML / OCL in GME for CNC system meta-modeling. For the field characteristic analysis for CNC, a CNC field oriented CNCVFC meta-modeling methodology was proposed, which combined the view, feature, component three-dimensional relationship. According to field characterization CNC members and interactions, multi-view approach captures features CNC field was adopted, which mapped to the appropriate view plane to establish the appropriate view of the container field meta-model, CNC elaborated meta-modeling process, including structural meta-modeling, function meta-modeling and non-functional meta-modeling of three areas. A lathe CNC system model was used as an example to verify the correctness of the meta-modeling methodology and modeling process for the CNC system customization and rapid development which provided a new methodology.
