Responsively responding to the ever-changing market of globalization, developing and producing new products accepted by users in the shortest time, and seeking survival and development in the competition has become the common goal pursued by companies. In order to adapt to the dynamic changes in the global market, the competition in the manufacturing industry in this century will be a competition of flexibility and responsiveness. Therefore, agile manufacturing is called the main mode of manufacturing in this century, and the virtual enterprise is an important means to realize agile manufacturing. The organizational model of the century and the important way of modern enterprise cooperation, and the networked design and manufacturing are the main working methods of the virtual enterprise. With the development of information technology and network technology represented by the Internet, the world economy is undergoing a profound revolution. This revolution shapes a "new world economy", namely "network economy". It is characterized by the fact that the information industry will develop greatly around the world. The process of globalization of the world economy will be greatly accelerated. The market of any country will become too narrow, the cross-nation and cross-industry joint development of enterprises will further develop, and economic activities will be organized according to networks. See the table to the right. Table Changes in Manufacturing Environment Traditional Economy Times Network Economy Times Relatively Stable Market Dynamics, Fast and Changeable Consumers Selective Locality Global Production Needs High Quality, Low Cost, Satisfies Basic Life Needs, Individualization, Diversified Production Methods, Standardization, Serialization High-volume single-item, small-batch, multi-variety technologies and resources are relatively concentrated. Globally distributed competitive factors Performance and price ratio Flexibility and response speeds can be seen from the table. The application of Internet technology to build a virtual enterprise, virtual design and virtual manufacturing are Imperative. Make full use of computers and rapid development of network technologies, and adopt the main organizational model of this century—virtual enterprises will be the best way for companies, especially small and medium-sized enterprises, to improve their competitiveness in the era of fast, changeable and unpredictable Internet economy. The only way to economic benefits. 1 Virtual design and virtual design The main technical content of virtual design includes: engineering analysis, virtual sample preparation, networked collaborative design, virtual assembly and interactive visualization of design parameters. Virtual reality technology is a human-computer interaction system based on natural methods. It uses a computer to generate a virtual environment and uses multiple sensing devices to provide users with an immersive feeling. The main features of virtual design can be summarized as follows: Integration. Combining multimedia technology such as three-dimensional dynamic display, simulation, and simulation of actual conditions, designers can seamlessly integrate into the virtual environment and experience the design process and performance of the product immersively, thereby becoming part of the virtual environment. Simplicity. The natural human-computer interaction method, WYSIWYG, uses realistic immersive feelings to support different user backgrounds, supports concurrent engineering, enriches design concepts, provides new design methods and stimulates design inspiration. Multi-channel communication. Designers experience a wide range of information such as sight, hearing, touch, and smell, exploiting their multiple potentials and increasing the success of their designs. Multiple interactive means. Get rid of the traditional mouse and keyboard input methods. Use a variety of interactive means (data gloves, voice commands, etc.) to support more design behavior (modeling, simulation, prediction, evaluation, etc.). real-time. The real-time participation, interaction, and display promote people's activities in the CAD environment to actively participate in active activities that integrate the human and the machine, forming an integrated intelligent development system. The virtual design application virtual prototype replaces the physical prototype and is visualized. It has been applied to many design fields that require high reliability, high precision, high physical model cost, and imitation of actual operating conditions. "Integrated Design Environment" is the interconnection of virtual environment and design. By establishing a three-dimensional digital model, designers use virtual reality equipment to directly guide the manipulation model in a virtual environment. Through virtual assembly, real-time collision detection, part penetration prevention, and three-dimensional tolerance evaluation of assembly can be achieved. 2 Virtual Manufacturing Virtual manufacturing relies on digital modeling, simulation technology, and virtual reality technology to simulate the system and process at every level of the plant within the virtual enterprise, and "make" the product on the computer. Its purpose is to use the modeling and simulation technology to simulate the product's future manufacturing process in a timely and parallel manner in the product design phase. Even the impact of various activities throughout the product life cycle on product design, prediction, detection and evaluation of the product can be manufactured Sex etc. Virtual manufacturing has the following features: Integration. It integrates a variety of related technologies such as digital modeling, visual simulation, manufacturing integration planning, enterprise resource planning, and optimization evaluation. Dynamic. In a three-dimensional, multi-view, multi-channel virtual environment. The simulation of manufacturing systems and processes can reflect the dynamic characteristics of actual system operations. It is beneficial to the design of designers and technologists and the training of future operators. Authenticity. By using virtual reality technology, the mapping from real manufacturing to virtual manufacturing can be realized and human initiative can be brought into play so that all participants can engage in and experience various activities in real manufacturing in the virtual environment. Predictive. Various virtual technologies such as virtual assembly and virtual operation can be used to perform structural design verification, real-time collision detection, and so on, thereby predicting many problems that may occur in the actual work in the future. 3 The continued maturity of the World Wide Web or World Wide Web (WWW) technology has made the Internet the most popular and convenient mass media at the moment. It is easy to store and access information. In addition, another kind of enterprise intranet Intranet has also seen rapid development in recent years. Intranet is a private network and information system infrastructure for the internal use of the Internet (mainly WWW) technology. The advantages and disadvantages of the above-mentioned virtual information system for virtual design and virtual manufacturing are the key to whether the entire virtual system can operate efficiently and reliably. Adopting the cross-platform TCP/IP protocol Internet technology brings the following advantages: Cross-platform technology is conducive to the integration of enterprises and enterprises. Due to the different tasks within each company and the internal departments of the virtual enterprise, the various types of workstations and numerous microcomputers used in the virtual enterprise have their own unique software and hardware systems, and only the cross-platform TCP/IP protocol. Internet/Intranet technology can effectively integrate the entire system. The establishment, operation and maintenance of the system are easy and the cost is low. The Internet/Intranet-based information system can build a support platform for the system at a very low cost, and the technical input costs are small: the network is robust and extensible. This reduces the cost of building a virtual enterprise. High degree of standardization. The unified user interface, unified language format, unified transmission protocol, and easy to use and maintain operations are not only conducive to improving work efficiency within the virtual enterprise, but also facilitate the user's full participation in the design and manufacturing process, thereby maximizing customer satisfaction. The system is powerful and there are many ways to share information, quickly and quickly. The Internet/Intranet-based information system enables the virtual enterprise's internal and external collaboration to be completed quickly and efficiently. The system supports multimedia information such as data, sound, graphics, and images, provides WWW preview, file transfer functions, information publishing, e-mail, user and security management, network news services, data processing and query and other script functions for virtual design and virtual Manufacturing provides basic services for system support platforms.
