Digital manufacturing refers to the digitalization of manufacturing field, which is the result of the intersection, integration, development and application of manufacturing technology, computer technology, network technology and management science, and it is also the inevitable trend for manufacturing enterprises, manufacturing systems, production processes and production systems to realize digitalization continuously.
It includes three parts: digital manufacturing centered on design, digital manufacturing centered on control and digital manufacturing centered on management.
For manufacturing equipment, its control parameters are all digital signals. For manufacturing enterprises, all kinds of information (such as graphics, data, knowledge, skills, etc. With the support of digital technologies such as virtual reality, rapid prototyping, database and multimedia, we can quickly collect information according to market information, analyze, plan and reorganize product information, process information and resource information, and realize product design and product function simulation. For the global manufacturing industry, users publish information through the network, and all kinds of enterprises apply e-commerce through the network according to their needs, so as to realize complementary advantages and form a dynamic alliance to jointly design and manufacture corresponding products quickly. In this way, in the digital manufacturing environment, a digital network has been formed in a wide range of fields, even across regions and borders. Enterprises, workshops, equipment, employees, dealers and even related markets can all become a "node" on the network, which interacts with each other in the process of research, design, manufacturing, sales and service, and becomes the most active factor driving manufacturing activities around the digital information given by products. This is "automation", that is, the technology or means to reduce human labor, strengthen, expand and replace human labor. Automation is always accompanied by related machinery or tools. It can be said that machinery is the carrier of all technologies and also the carrier of automation technology.
"Automation" has developed from automatic control, automatic adjustment, automatic compensation and automatic identification to higher-level automation such as self-learning, self-organization, self-maintenance and self-repair. Moreover, the connotation and level of today's automatic control is far from the past, and great progress has been made in control theory, control technology, control system, control components and so on. The automation of manufacturing development not only greatly liberates people's physical labor, but also effectively improves mental labor and liberates some people's mental labor. Therefore, automation will be a prerequisite for the development of modern integrated manufacturing technology. "Integration" refers to the integration of technology, management and technology and management. Its essence is the integration of knowledge, that is, the integration of knowledge expressions. As mentioned above, modern integrated manufacturing technology is the integration of manufacturing technology, information technology, management science and related science and technology. "Integration" means "crossing", that is, "hybridization", that is, learning from each other's strengths.
"Integration" mainly refers to:
(1), integrating modern science and technology. Electromechanical integration is a typical example, which is the basis of high-tech equipment, such as microelectronics manufacturing equipment, information and network products and supporting equipment, instruments, meters, medical, biological, environmental protection and other high-tech equipment.
(2), integrated processing technology, special processing technology and its equipment are typical examples, such as additive manufacturing (that is, rapid prototyping), laser processing, high-energy beam processing, electro-machining, etc.
(3) Enterprise integration, that is, management integration, including the integration of production information, functions and processes; Including the integration of production processes. Integrate the whole life cycle process; It also includes the integration within the enterprise and the integration outside the enterprise. Intelligent manufacturing technology is the prospect of manufacturing technology development. The basis of intelligent manufacturing mode is intelligent manufacturing system, which is not only the application environment formed by the integration of intelligence and technology, but also the carrier of intelligent manufacturing mode. Compared with traditional manufacturing industry, intelligent manufacturing system has the following characteristics: 1, man-machine integration; 2. Self-discipline; 3. Self-organization and super-flexibility; 4. Learning ability and self-maintenance ability; 5, in the future, have a more advanced humanoid thinking ability.
The intelligentization of manufacturing technology is manifested in all aspects of manufacturing. With the help of the intelligent activities of human experts simulated by computer, analysis, judgment, reasoning, conception and decision-making are carried out in a highly flexible and integrated way, which replaces or extends part of human mental work in the manufacturing environment. At the same time, we will collect, store, process and improve, and enjoy, inherit and develop the manufacturing wisdom of human experts. Although intelligent manufacturing has a long way to go, it will surely become one of the main production modes in the future manufacturing industry. "Green" is quoted from the field of environmental protection. The development of human society will inevitably lead to the harmony of human social and natural. Human beings and human society are essentially part of nature, and some of them cannot be separated from the whole, let alone confront and destroy the whole. Therefore, human beings must promote the harmony between people and human social and natural from all aspects, and manufacturing technology is no exception.
From concept to design, manufacture, sale, use and maintenance, and then to recycling and remanufacturing, products of manufacturing industry must fully consider environmental protection. The so-called environmental protection is broad, not only protecting the natural environment, but also protecting the social environment and production environment, as well as protecting the physical and mental health of producers. Under this premise and connotation, we should also produce products with low price, good quality, short delivery time and good after-sales service. As a "green" manufacturing, products must also be works of art to a certain extent, so as to adapt to the user's production, work and living environment, give people noble spiritual enjoyment, and reflect the high integration of material civilization, spiritual civilization and environmental civilization. When developing and adopting a new technology, we should stand at the height of philosophy and think carefully about "a blessing in disguise is a blessing in disguise", that is, we should give full consideration to sustainable development and environmental civilization. The manufacturing industry is bound to move towards "green" manufacturing.
