MTConnect Enabled Interoperable Monitoring System for Finish Machining Assembly Interfaces of Large-scale Components

Monitoring is an important issue for finish machining the assembly interface of the large-scale component, as it plays a crucial role in ensuring security and reliability in the finish machining system. To overcome the interoperable problems caused by different proprietary interfaces and communication protocols, this paper proposes an MTConnect compliant monitoring system for acquisition and supervision of the pivotal data during the finish machining process. The framework of the finish machining system is introduced at first, in which the main components and the workflow are described. What is more, the vital procedure and the involved process data are pointed out. Then the MTConnect standard is used to model the finish machining system, including the architecture and the data items. Based on the presented MTConnect model, a web-based monitoring system is developed for data collection and monitoring while machining the assembly interface of the large-scale component. The validity and the interoperability of the proposed approach are verified by collection and monitoring of the process data during finish machining the assembly interface of a vertical tail.
