Summary: mechanical manufacturing Technology is not only a national science and Technology to measure an important indicator of the level of development is the focus of international technological competition. In this paper, the status of China's machinery manufacturing Technology and technical features of the analysis, and outlines the 21st century, the development of Manufacturing Technology direction.

Keywords:: mechanical characteristics of manufacturing Technology development

China is in a critical period of economic development, manufacturing technology is our weak link and only keep up with the world trend of advanced manufacturing technology, put it in the strategic priority, and in sufficient strength to be implemented in order to narrow and developed countries gap, to the fierce competition in the market in an invincible position.

First, the development of China's machinery manufacturing technology Analysis

Manufacturing Technology is the study of product design, production, processing, manufacturing, sales use, maintenance services and even recycling the whole process of Engineering disciplines, is to enhance quality, efficiency, competitiveness goals, including material flow, information flow and energy flow complete system Engineering.

20 Before the 1970s, the technology is relatively simple product, a new product, will soon follow the same functional product listed 20th century 80 years later, with the further development of the globalization of markets, market competition becomes more and more intense.

The early 1990s, with the CIMS technology to promote the Application, including the CIMS Engineering Center and seven experimental Laboratory research environment has been built in the country, has deployed a number of CIMS research projects, such as CIMS software Engineering and standardized, open system architecture and development strategy, CIMS overall and integrated technology, product design, automation, process design automation, flexible manufacturing technology, management information systems and decision-making, quality assurance, network and database technology and systems theory and methods etc achieved fruitful results, with varying degrees of progress. But most of the major machinery manufacturers and the vast majority of small and medium sized manufacturing enterprises mainly limited to mechanical CAD and management information systems, the underlying basis for automation is still very weak, NC Jichuang complex as programming, not really play a role. Therefore, compared with industrialized countries, China's manufacturing industry is still a gap on the whole stage.

At present, China has joined WTO, machinery manufacturing industry faces enormous challenges and new opportunities, therefore, China's machinery manufacturing industry along the 20th century, not simply based on cam its institutions using special tools, special fixtures, special tool consisting of flow-lines - rigid automation. but to develop a comprehensive, five-oriented development, namely, globalization, networking, virtualization, automation, green.


Second, the characteristics of Manufacturing Technology

Work to do basic automation manufacturing enterprises in China is still a very urgent and arduous task, but both the quantity and processing center utilization is very low. Programmable controllers use is not universal, the Application of industrial robots is still limited, so we must capitalize on China's actual situation, seeing the trends in international manufacturing, while a solid job work basis.

1 Manufacturing Technology is a systems Engineering
Advanced manufacturing technology with special emphasis on computer technology, information technology, sensor technology, automation technology, new materials technology and modern management systems in product design, manufacturing and production organization and management, sales and service and other Applications it will continue to assimilate the kinds of high-tech achievements and traditional manufacturing technology, the manufacturing technology to become able to control the production process of material flow, energy flow and information flow in systems engineering.

2. Manufacturing Technology is a comprehensive technical
Application of advanced manufacturing technology goals is to improve competition and promote national economic growth and overall strength, so it is not limited to the manufacturing process itself, which involves the product from the market research, product development and process design, production preparation, manufacturing, service and other product life-cycle of all content, and combine them into an organic whole. in order to improve the manufacturing of integrated economic and social benefits.

3. Machinery manufacturing technology is the unity of the elements of market competition
Market competition is the core of how to improve productivity. With the further development of the globalization of markets, since the 1980s, the manufacturing industry to win the main contradiction of market competition has changed from increasing labor productivity with time as the core of the time, cost and quality the three elements of the conflict. advanced manufacturing technology to combine these three conflicts, the three reached unity.

4. Manufacturing Technology is a worldwide technology
Since the 1980s, with the formation of the global market, developed by financial, economic, scientific and technological means for the market, dumping products, export of capital, making the market competition becomes increasingly fierce, as fierce competition in the market to adapt to this, a state of advanced manufacturing technology should have the world advanced level, should be able to support the country's manufacturing competitiveness in the global market while manufacturing technology is 21st century technology should be combined with modern high-tech, should have specific areas of new technology.

Manufacturing technology, advanced manufacturing technology is the latest stage of development, from traditional manufacturing techniques developed, while maintaining the manufacturing technology in the past the effective elements, but also continue to absorb a variety of high-tech achievements, and penetrate into all areas of production and the whole process.

1980s, with the scanning microscope of the invention and use of human knowledge and the ability to transform the world into the nanoscale, nanotechnology refers to the realization of nanometer-level precision, is a kind of nano-scale atomic and molecular structure, physical properties and interaction with the movement, and use this technology for human services a high-tech, nano-technology manufacturing industry had a great impact, it will be very broad range of Applications, including nano-materials technology and nanofabrication technologies, nano-assembly technologies and nano-measurement technology.

Ultra-precision machining of precision reached in 2000, nano-scale, developed in the early 21st century the growth of molecular beam techniques, ion implantation technology and materials synthesis, scanning tunneling engineering (STE precision can reach 0.0003 ~ 0.0001μm, now Precision Engineering forward its ultimate goal - approaching atomic-level precision machining, that can be moved at the atomic level of processing.

Modern machinery manufacturing technology development is mainly manifested in two directions: First, precision engineering technology to the forefront of ultra-precision machining parts, micro-machining, nano-technology as the representative, will enter the micro-electronics and micro-mechanical robot era, two is highly automated machinery to CIMS and the further development of agile manufacturing as the representative.

1 precision forming technology prototyping and manufacturing technology, including casting, welding, plastic processing, etc. precision forming technology include: Casting (wet film forming precision casting, precision forming just type casting, precision-made core), precision forging (cold wet precision forming , fine blanking, precision thermoplastic forming, precision welding and cutting.

(2) no cutting fluid processing without cutting fluid for processing major applications is the machining industry, no cutting fluid processing to simplify the process, reduce costs and eliminate a series of problems caused by the cooling fluid, such as emissions and waste recycling, etc. .

3 Rapid Prototyping Rapid prototyping parts manufacturing (RPM, designed to break through the traditional processing techniques used in material removal principle, and used to add, cumulative principle its representation of technology Laminated Object Manufacturing (LOM), melting deposition manufacturing (FDM, and so on.

Because of these processes and technologies not only reduce the consumption of raw materials and energy, or shorten the development cycle, reduce costs, improve processes and some protective effects on the environment, it is called the green manufacturing process of green manufacturing is the human community can sustainable development reflected in the manufacturing sector, which all in addition to technology innovation, but also must rely on information technology through computer simulation, the simulation can be achieved.


CONCLUSIONS

Modern technology and modern manufacturing technology is the integration of industrial innovation, is the country's main indicator of the level of the manufacturing sector, but also the country's industrial base and pillar. With the development of society, demand for products has also undergone great changes, requiring species to be diverse, update to fast, high quality to use to be convenient, reasonable prices, appearance to appearance, higher degree of automation, better service, to meet increasing demands, we must adopt advanced manufacturing technology Therefore, we should seize the opportunity to understand China's machinery manufacturing technology development status, to grasp the modern machinery manufacturing technology trends so that our modern manufacturing and the world's developed countries on the same starting line.
