附录附录1NC technology and equipment, trends and countermeasures -Alexander LudwigAbstract: This paper describes the current world NC technology and equipment and the development trend of Chinas CNC equipment and technology development and industrialization of the status quo, based on this discussion in Chinas WTO accession and opening up further deepen under the new circumstances, the development of China NC technology and equipment, and enhance the countrys information industry and the level of international competitiveness of the importance of strategy and tactics from the two dimensions of the development of Chinas technology and equipment NC Viewpoints. Industrial equipment of the technological level and degree of modernization of the national economy as a whole is determined by the level and degree of modernization, NC technology and equipment is the development of new high-tech industries and cutting-edge industries (such as information technology and related industries, biotechnology and related industries, aviation, aerospace and other defense industrial) enabling technology and the most basic equipment. Marx once said that the difference between various economic times, what is not production, and production is how, what labor production. Manufacturing technology and equipment, is the most basic of human activities in the production of capital goods, and numerical control technology is todays advanced manufacturing technology and equipment, the core technology. The world today manufacturing CNC technology widely used to enhance manufacturing capability and the level of increase on the dynamic ability to adapt to changing market and competitive ability. In addition to the worlds industrialized countries will NC NC technology and equipment as a national strategic commodities, not only to take significant measures to develop its own CNC technology and its industries, but also in the high-tech key technology and equipment NC aspects of the implementation of Chinas policy of closures and restrictions. In short, vigorously develop its NC technology as the core of advanced manufacturing technology has become the worlds least developed countries to accelerate economic development and enhance the overall national strength and an important way to statehood. NC technology is the use of digital information on the mechanical movement and the work process control technology, NC NC technology equipment is the representative of new technologies on traditional manufacturing industries and new manufacturing formation of the infiltration of electromechanical integration products, the so-called Digital equipment, and its technical covering many areas: (1) Machinery Manufacturing Technology (2) information processing, processing, transmission technology, (3) automatic control technology, (4) servo drive technology; (5) sensor technology; (6) software technology. 1 NC technology development trends NC technology applications not only to the traditional manufacturing sector has brought revolutionary changes in the manufacturing industry as a symbol of industrialization, and along with the constant development of NC technology and the expansion of the area of application, he comes to some important sectors (IT , automobiles, light industry, health care, etc.), playing an increasingly important role in these industries because of digital equipment needed is the development of the modern trend. Judging from the current NC Technology and the world view of the trend of the development of equipment, and its main research focus in the following areas 1 4. 1.1 high-speed, high-technology and equipment finishing the new trend Efficiency, and quality is the main body of advanced manufacturing technology. High-speed, high-finishing technologies can greatly improve the efficiency, improve product quality and grades, shortening the production cycle and improve market competitiveness. For this reason Japan will tip its technology research as five of the modern manufacturing technology, and international production Engineering Society (CIRP) will be identified as the center of the 21st century one of the research directions. In the car industry, the annual production of 300,000 is 40 seconds beats / units, and car variety processing equipment is the key problems must be solved one of the aviation and aerospace industry, processing for more than thin-walled parts and the thin line, stiffness poor material for aluminum or aluminum alloy, and only in high cutting speed cutting force small circumstances, can these tendons, wall processing. Recently a large overall aluminum alloy billets hollowing out approach to manufacture wings, fuselage and other parts to replace large number of parts by many rivets, screws and other foodstuff to connect to the component strength, stiffness and reliability has been upgraded.
