A framework for model-based integrated inspection

To promote the integration of design, manufacturing, and inspection as well as to improve the efficiency of manufacturing and ability of quality control, a concept of model-based integrated inspection was proposed and a framework was constructed in this paper. The framework consists of the device layer, data layer, application layer, and operation layer. A united interface model for the connection of inspection equipment and inspection system was put forward, which is taken as the basis of the device layer. Information from inspection processes is integrated into the product model, which makes up the data layer. The activities of model-based integrated inspection are encapsulated in the application layer. The operation layer provides system operation and management for the framework. Based on the framework, a prototype system was developed, which combined process-oriented inspection and quality verification-oriented inspection. In the end, a case study of a helicopter part was given to expound the application and the advantages of the proposed framework.
