[Abstract]:The wide interconnection and interoperation of manufacturing equipment is an important prerequisite to realize wide connection in manufacturing field. It is a hot point to collect the heterogeneous data of NC system such as machining parameters, tool geometry parameters, parts quality inspection and so on, and to monitor the NC system effectively. Based on OPC (object linking and embedding for process control) UA (unified architecture) to connect numerical control system, a real-time monitoring system of "adapter-agent (adapter-agent)" based on MTConnect is established. The real-time monitoring data model, communication framework and access strategy are studied, and the standard data model of machine tool process monitoring data is given. The prototype system is used to monitor and control the actual machining process of an aviation thin-walled part in real time. The integrated visual expression of machining process data and off-line data is realized, and the effectiveness of the information integration method of the proposed numerical control system is verified. The data model constructed by this method clearly expresses the processing elements and has good expansibility.
