Characteristics and Development of Modern Manufacturing Technology

Today's society is experiencing rapid industrial development. The diversity and frequent changes of social needs make various manufacturing technologies parallel, while traditional energy and market competition are increasingly tense, these changes in the objective environment pose acute challenges to the traditional machinery industry, forcing the machinery industry to speed up product updates and development, in order to make full use of the latest achievements of modern science and technology, in accordance with the high efficiency, high quality, low cost requirements to continuously produce a variety of energy-saving new products. At present, all countries in the world are exploring advanced manufacturing technologies. So advanced manufacturing technology is the integration, integration and penetration of many technologies, such as manufacturing technology, electronic technology, information technology, automation technology, energy technology, material science, and modern management technology.. It involves the whole process of product lifecycles in the manufacturing industry, such as product design, processing and assembly, inspection and testing, operation management, and marketing, to achieve high-quality, efficient, low-consumption, clean, and flexible production, this is a comprehensive technology to improve the adaptability and competitiveness of dynamic and changing markets. Taking the automobile industry as an example: At present, the number of people in China's automobile industry has reached more than 1.8 million. In 2001, the number of cars produced was 2.255 million. In Japan, only 0.5 million people were employed, but the number of cars produced was as high as 13 million, in contrast, the average output of China's automobile industry is only L/20-l/30 of Japan. By, China's automobile production exceeded million vehicles. In December 2009, Japanese cars produced more than 9.8 million vehicles. 60 years after the founding of the People's Republic of China, China's automotive industry has grown from its initial growth, accelerated growth, and rapid growth to rapid growth, it has experienced four historic breakthroughs that span an annual output of 1 million vehicles, 2 million vehicles, 3 million vehicles, and 10 million vehicles. The l000 vehicles are a key node from quantitative to qualitative changes, which fully demonstrates that the development of modern manufacturing technology has a powerful restraining and promoting effect on the development of a country's industrial modernization. Computer technology, numerical control technology, control theory and system engineering and manufacturing technology are combined and applied to form a modern manufacturing engineering system. Three basic elements of modern manufacturing systems: Material Flow, traffic flow, and information flow. For a long time, the various problems involved in the production process are often studied and solved in isolated ways, which makes our technology and management work tend to be messy and lack the overall advantages, therefore, it is difficult to obtain the best solution, which is particularly prominent in Small and Medium batch production. In modern mechanical manufacturing, people are increasingly aware that only the whole process of mechanical manufacturing and its components are regarded as a whole. Only by analyzing and researching from a systematic point of view can we implement the most effective management and control of the mechanical manufacturing process to achieve the best economic effect. 1. At present, the characteristics of modern manufacturing technology are classified as three types of first. manufacturing and processing have become an independent manufacturing system, and timely production has become a new concept of the current manufacturing system. Parallel engineering is an integrated and parallel design product. In the process of product manufacturing, processing, and production, the product design and development personnel, from abstract thinking to concept theory formation, manufacturing, processing, and production in practice, and continuously improve the product design and processing. To the successful R & D, a large number of production and sales operations, and the end-to-end product life. All factors throughout the production and use cycle are the products produced according to users' needs. Therefore, it is a dynamic optimization method to solve the problem. Lean Production is a product in development and production, streamlining the Organization, optimizing staffing, and maximizing economic benefits. To improve the market competitiveness of enterprises. Agile Manufacturing uses computer intelligence and information technology to change the traditional complex hierarchical structure to achieve mass mechanical production. Second, design and process integration. When humans are engaged in small-scale manual labor production, the product production design and manufacturing process are designed and produced by the same person, low efficiency production lags behind. Large-scale mechanical production is required for production. The design is separated from the process, and the process belongs to the design phenomenon. With the development and improvement of human social living standards, Multiple Varieties of single-piece and small-batch mechanical production account for a large proportion in the production process. The specifications and styles of products are constantly updated, and the demand for product diversity is growing, resulting in integration of design and process. Third, the formation of manufacturing science. The most urgent task of manufacturing technology is to develop the scientific and systematic theoretical basis it needs in the production process. The current manufacturing technology is based on science and relies on theories, algorithms, experiments, analysis, models, simulations, simulations, and other means to develop and deepen its connotation, the information flow and material flow between the expression function and the model are established. We can analyze and control the manufacturing system. Only by identifying the potential rules of the performance of the manufacturing science can we predict the impact of changes in the situation. Manufacturing Science is a comprehensive science developed from the organic combination of mechanical principles, computers, information, materials, automation, and other disciplines. It is based on mechanical principles. The development and application of computer technology accelerates the formation of manufacturing science. The development of manufacturing technology and the emergence of manufacturing systems are prerequisites and essential for the formation of manufacturing science. 2. The content and development direction of modern manufacturing technology can be discussed in five aspects: (1) Automation, integration and intelligence of mechanical manufacturing systems. The mechanical manufacturing process is a discrete production and processing process, compared with the continuous production process. Automation is more difficult. Single Machine Automation, rigid automatic lines, numerical control machine tools and machining centers, flexible manufacturing systems and computer integrated manufacturing systems form a mechanical manufacturing automation, and to flexible, integrated, intelligent development. The purpose of automation is not only to improve production efficiency and labor conditions, but also to ensure the quality of products produced by mechanical manufacturing automation. (2) precision engineering. It includes precision processing and ultra-precision processing technology, micro-processing and ultra-fine processing technology, micro-machinery and nano-technology. At present, the ultra-precision technology represented by nano technology and micro-mechanical technology using micro-processing as the means are of great significance, they represent the direction of precision engineering in this period. (3) Non-traditional processing methods. Traditional processing methods, also known as special processing methods, are physical and chemical processing methods. Processing and manufacturing methods include separation, adhesion, and deformation, as well as changes in the chemical composition, microstructure, and mechanical properties of mechanical workpiece surface layers. The main object of the special processing method is the workpiece of super-difficult processing materials. Such as diamond, ceramics and other super-hard materials, the processing accuracy can reach the molecular level processing unit or atomic level processing unit, so it is often an important means of precision processing and ultra-precision processing. At present, laser processing, electron beam processing, and ion beam processing are the most important items in special processing. (4) Quick prototyping and manufacturing parts are a three-dimensional entity which can be formed by the superposition of several "faces" in a certain direction. Therefore, the concept of discrete/Stacked forming forms the basic principle of rapid forming manufacturing. There are many specific manufacturing methods, and mature commercialization methods include stratified entity manufacturing and stereo photography. (5) innovation and improvement of traditional processing and manufacturing processes. Modern manufacturing technology has great potential for technological improvement in traditional manufacturing processes, such as high-speed cutting, ultra-high-speed cutting, high-speed grinding, and powerful grinding, for example, transforming a common machine tool into a numerical control machine tool can not be ignored in the development and improvement of the modern manufacturing machinery industry. The emergence and application of modern manufacturing technology has far-reaching significance for the development of processing theory and the improvement of processing quality and production efficiency in practice. While entering the new century, human society has gradually entered the era of knowledge economy from the era of industrial economy. The global economy is in a period of dynamic change, and the manufacturing industry is facing more severe challenges. In the era of knowledge economy, knowledge and technology are considered to be the driving force to increase productivity and achieve economic growth. Therefore, advanced manufacturing technology has become a key factor for manufacturing enterprises to remain invincible in the fierce market competition and to achieve rapid development. It has become an important support for the development of the world economy and to meet the increasing needs of mankind, it has become a booster for accelerating the development of new and high technologies and realizing the modernization of national defense.
