Abstract：As the only basis for the manufacturing process, MBD model has gradually become the development
trend of the aviation manufacturing industry, and it has been applied to the CAD/CAM system. However, MBD technology
has not been used in the CAPP, which results in the poor information flow of the MBD data set during the integration
of CAD/CAPP/CAM. In this paper, according to the requirements of NC machining of the aviation structure, the MBD NC
machining process model is built based on layers. The work flow of NC machining process based on MBD is proposed. The
CAPP system of NC machining based on MBD is researched and developed. The MBD application of integrated design and
manufacture on UG platform is realized finally.
