6. The development trend of mechanical manufacturing technology can be summarized as follows: (1) Machine manufacturing automation. (2) Precision Engineering. (3) The improvement of traditional processing methods and the development of non-traditional processing methods.
Mechanical manufacturing automation technology has always been one of the most active research areas in mechanical manufacturing. It is also the main means for manufacturing companies to increase their productivity and win market competition. Since its emergence in the 1920s, mechanical manufacturing automation technology has gone through three stages, namely rigid automation, flexible automation and comprehensive automation. Integrated automation is often associated with concepts such as computer-aided manufacturing and computer-aided manufacturing. It is a combination of manufacturing technology, control technology, modern management technology, and information technology. It aims to comprehensively improve labor productivity and responsiveness of the manufacturing industry to the market.
First, integrated
Computer Integrated Manufacturing (CIMS) is considered to be the main production method for manufacturing companies in the 21st century. CIMS is composed of several interconnected parts (sub-systems), usually divided into 5 parts.
Points: 1. Engineering Technology Information Sub-system
Including Computer Aided Design (CAD), Computer Aided Engineering Analysis (CAE), Computer Aided Process Planning (CAPP), Computer Aided Tooling Design (CATD) NC Programming (NCP)
Wait. 2. Management Information System (MIS)

5. Computer Network and Database Subsystem (Network & DB)
It is a support system for linking the above several sub-systems to achieve the integration of sub-systems.
Second, intelligent
Intelligent manufacturing system can be understood as a human-machine integrated intelligent system composed of intelligent machinery and human experts. The system can carry out intelligent activities in the manufacturing process, such as analysis, reasoning, judgment, conception, decision-making and so on. In smart systems, "smart" is mainly reflected in the system's excellent "soft" features (adaptability and friendliness). In the design and manufacturing process, a modular approach is used to make it more flexible; for people, intelligent manufacturing emphasizes safety and friendliness; for the environment, it requires no pollution, energy and resources are fully recovered; for the society , promote reasonable cooperation and competition.
Third, agility
Agile manufacturing is based on competitiveness and credibility, choosing partners to form a virtual company, division of labor and cooperation, working together for the same goal to enhance the overall competitiveness, and respond quickly to user needs to meet the needs of users. In order to achieve rapid adaptability, the establishment of a virtual enterprise is a key technology, and its core is virtual manufacturing technology, that is, agile manufacturing is based on virtual manufacturing technology. Agile manufacturing is the only way for modern integrated manufacturing systems to develop from information integration to enterprise integration. Its development level represents the development level of modern integrated manufacturing systems and is the development direction of modern integrated manufacturing systems. The technical foundation for agile manufacturing includes:
1. A large-scale communication infrastructure requires the establishment of a factory-wide information network and Just-In-Time-Information system nationwide.
2. Flexible, modular product design methods. 3. Highly flexible, modular, scalable manufacturing system. 4. The production method designed and manufactured for the order. 5. Task-based organization and management. 6. Trust-based employment relationships.
Fourth, virtualization
The concept of "virtual manufacturing" was introduced in the early 1990s. Virtual manufacturing is based on system modeling and computer simulation technology. It integrates modern manufacturing processes, computer graphics, information technology, concurrent engineering, artificial intelligence, and multimedia technologies. It is an integrated system formed by multidisciplinary knowledge. technology. Virtual manufacturing utilizes information technology and simulation computer technology to conduct a comprehensive simulation of humans, objects, information, and manufacturing processes in actual manufacturing activities to discover possible problems in manufacturing and take preventive measures before actual production of the products to achieve The products were successfully manufactured at one time to reduce costs, shorten product development cycles, and enhance product competitiveness.
V. Cleanliness
Cleaner production refers to the application of an integrated prevention environmental strategy to production processes and products in order to reduce risks to humans and the environment. The two basic goals of clean production are the comprehensive utilization of resources and environmental protection. For the production process, clean production requirements penetrate the entire process from raw material input to output of finished products, including saving raw materials and energy, replacing toxic raw materials and shortage resources, utilizing secondary energy and renewable resources, and improving processes and equipment. And reduce the amount and toxicity of all emissions before leaving the production process. For products, clean production coverage constitutes all stages of the product's entire life cycle, from the extraction of raw materials to the final disposal of products, including product design, production, packaging, transportation, distribution, sales, and scrapping, and the rational use of resources. And minimize the adverse effects on humans and the environment. In summary, the direction of the development of the machinery manufacturing industry is to organically combine traditional manufacturing technologies with modern information technology, management technology, automation technology, and system engineering technology. Computer technology is the relevant organization of the enterprise product throughout its life cycle. , Operations, management, and technology are organically integrated and optimized to operate. In the entire product life cycle of the company's products, information, intelligence, and integration are optimized to achieve rapid product launch, good service, and low quality and high cost. This will increase the flexibility and robustness of the company. Sex and agility are companies that are invincible in the fierce market competition.
