With the rapid development of information technology and computer network technology, the world economy is undergoing a profound revolution. This revolution has greatly changed the face of the world economy and shaped a "new economy", that is, "network economy." In the face of changes in the manufacturing environment in the era of network economy, it is necessary to establish a networked manufacturing system model that is driven by market demand and has a rapid response mechanism. Networked manufacturing is an inevitable move taken by the traditional manufacturing industry in the network economy. Manufacturing companies will use the Internet for collaborative product design and manufacturing. Through the Internet, companies will be in direct contact with customers, customers will participate in product design, or direct orders to enterprises for customized production, the company will directly sell products to customers. As the Internet is ubiquitous, market globalization and manufacturing globalization will be an important part of the company's development strategy. Due to the rapidity of information transmission on the Internet and due to the fierce changes in the manufacturing environment, cooperation among enterprises has become more frequent and the resources of enterprises will be used more fully and reasonably. The information and knowledge in the enterprise will be highly integrated and shared, and the management mode of the enterprise will change greatly. Therefore, networked manufacturing will become an important manufacturing strategy for manufacturing companies in the 21st century.
Networked manufacturing technology is the general term for all related technologies and research fields that combine network technology and manufacturing technology (emphasis is on advanced manufacturing technology), and is an inevitable outcome of the era of economic globalization and information revolution. Networked manufacturing technology is not a specific technology, nor is it an inflexible single technology, but an evolving dynamic technology group and dynamic technology system. It is based on computer networks, especially Internet/Intranet/Extranet and databases. The general name of advanced manufacturing technology. The networked manufacturing technology involves various manufacturing operations of the manufacturing industry and the entire process of the product production cycle. Therefore, its technical composition involves many contents and the scope of the disciplines is large. But generally speaking, "network-based" is his main feature compared to other manufacturing technologies. This feature shows the basic role and supporting role of the network. Networked manufacturing technology is not only an important high and new technology, but also a combination of information technology and manufacturing technology. It is an important and effective technology that drives information technology into industrialization. The current research and application of related technologies related to networked manufacturing have developed rapidly in developed countries. China's manufacturing industry should also fully understand the severe competition situation and potential latecomer advantages faced, that is, the situation in which challenges and opportunities coexist. Through the development of networked manufacturing technology, we can improve the management level of our country's enterprises, as well as the ability to develop international and domestic markets, and improve our product development capabilities; we can accelerate the adjustment of China's industrial structure; improve the utilization of manufacturing resources in China, reduce manufacturing costs, and improve China's The manufacturing capacity and manufacturing level of the enterprise are conducive to the overall optimization of the operations of our company and improve the overall level and overall efficiency. Therefore, we must seize the opportunity to develop key technologies for networked manufacturing, use networked manufacturing technologies to transform and upgrade our traditional manufacturing industries, and use information technology to drive manufacturing.
Second, the composition of networked manufacturing systems
Networked manufacturing involves collaboration, design, service, sales, and assembly. It consists of the following functional subsystems: an optimized system of networked enterprise dynamic alliances and virtual enterprise formation; a project management system in a networked manufacturing environment; networked collaborative products Development support system; product data management and design and manufacturing integrated support system under networked manufacturing environment; agile supply chain management system under networked manufacturing environment; product networked sales and customization development and operation support system; corresponding network and database support points system. These functional subsystems can be integrated and operated individually. At the system level, from the bottom up, the basic network transmission layer (the system can use Internet connections, internal and external network connections, and regional broadband network connections), database management systems, basic communication platforms for search and analysis, project management and PDM ( Functional subsystems), user-oriented application systems and services. Its structure is shown in Figure 1.

Third, the key technologies of networked manufacturing
1. Agile Infrastructure Network for Manufacturing Systems (AIMSNet, Agile Infrastructure for Manufacturing System)
AIMSNet includes pre-commissioning and pre-qualification, supplier information, resource and partner selection, contract and agreement services, virtual enterprise operations support, and working group cooperation support. AIMSNet is an open network where any company can provide services, and this network is seamless because it does not make any difference between a company's internal and external services. Through AIMSNet, production preparation time can be reduced, current production can be made smoother, and new ways for companies to engage in production activities can be opened up. The use of AIMSNet can connect large, medium and small enterprises with complementary capabilities to form a supply chain network. Businesses are no longer "big and full" and "small and all-inclusive," but are more focused on their core expertise. Through mutual cooperation, it can effectively handle any unpredictable market changes.
2. CAM Network (CAMNet)
CAMNet provides a variety of manufacturing support services through the Internet, such as product design for manufacturability, process simulation, and product testing, enabling members of integrated companies to quickly connect and share manufacturing information. The establishment of agile manufacturing support environment is coordinated on the network, and various distribution information stored in the database in the database text graphics and data files is integrated by the enabler for sharing by partners, thereby providing support for the process integration of various cooperative enterprises.
3. CAPP technology in networked manufacturing mode
CAPP is the bridge and link between design and manufacturing, so the implementation of networked manufacturing system must be supported by process design theory and its application system. Therefore, on the basis of inheriting the research results of the traditional CAPP system, further exploration of the integrated, instrumentalized CAPP system under the networked manufacturing model is the frontier area of ​​current networked manufacturing system research and development. It includes the establishment of an instrument-based input mechanism based on Internet, a derivative process design method based on the Internet, and a creative process design method based on the Internet.
4. Enterprise Integration Network
EnterpriseIntegrationNet offers a variety of value-added services, including directory services, security services, and electronic money transfer services. Directory services help users find information, services, and people within the electronics market or within the enterprise. Security services provide network security through user rights. Electronic money transfer services support business transactions across the entire network. Through these services, users can quickly determine the required information, conduct various services safely, and easily handle financial transactions.
