Implementations of Model Based Definition and Product Lifecycle Management Technologies: a Case Study in Chinese Aeronautical Industry

Abstract : The paper describes and analyzes the Model Based Definition (MBD) and Product Lifecycle Management (PLM) technologies and their related Computer-Aided X applications in order to enable the implementation of an integrated design and manufacturing system in Chinese aeronautical industry. Using the full three-dimensional technology allows the MBD specification of geometry, features and attributes for mechanical parts. It also supports an integrated design method for specifying MBD models of these parts. Considering the manufacturing specifications based on MBD, the feature machining and Coordinate Measuring Machine (CMM) control technologies are used for intelligent manufacturing of parts. Machining and quality inspection programs are automatically generated including the associated MBD process and quality models. Finally, the integrated design and manufacturing system based on MBD and PLM technologies is applied on the case study of an engine fan blade in order to assess the proposed method.
