Based on heterogeneous numerical control systems in the workshop layer, architecture of networked communication is established to meet the requirement of networked manufacturing. It realizes the integration and information interaction between shop floor equipment and upper layer application systems by integrating the information of the equipment layer with the workshop application layer. Networked communication mechanism of the architecture was constructed. Furthermore, information integration, i.e., integration of applied equipment, integration within enterprise based on Common Object Request Broker Architecture (CORBA), and integration between enterprises based on web Services, is also discussed in detail. Experiment demonstrates that the proposed system helps the information integration both within and between enterprises in the networked manufacturing system.
