Industrial technology and equipment modernization of the national economy as a whole is determined by the level and degree of modernization, CNC equipment is the development of new technology and cutting-edge industries and high-tech industries (such as information technology and its related industries Biotechnology and related industries, aviation, aerospace and other defense industries) enabling technology and the basic equipment. NC widely used in the world today manufacturing technology, to increase manufacturing capacity, enhance the ability to adapt to dynamic market changes and competitive ability. Besides the developed industrial world will NC NC equipment and technology as the strategic commodities. not taken significant steps to develop its own digital technology and its related industries in the "high-tech" NC key technology and equipment to China's policy of closures and restrictions. In short, numerical control technology at the core of efforts to develop advanced manufacturing technology has become the world's developed countries to accelerate economic development. improve our overall national strength and an important way to statehood. NC technology is the use of digital information to the mechanical and process control technology, NC NC technology equipment is represented by the new technologies on traditional manufacturing industries and the formation of the penetration of new manufacturing machinery and electronics products, the so-called digital equipment, technology cover many areas : (1) Machinery Manufacturing Technology; (2) information processing, processing, transmission technology; (3) control technology; (4) servo drive technology; (5) sensor technology; (6) software technology.
   装备工业的技术水平和现代化程度决定着整个国民经济的水平和现代化程度,数控技术及装备是发展新兴高新技术产业和尖端工业(如信息技术及其产业、生物技术及其产业、航空、航天等国防工业产业)的使能技术和最基本的装备。当今世界各国制造业广泛采用数控技术,以提高制造能力和水平,提高对动态多变市场的适应能力和竞争能力。此外世界上各工业发达国家还将数控技术及数控装备列为国家的战略物资,不仅采取重大措施来发展自己的数控技术及其产业,而且在“高精尖”数控关键技术和装备方面对我国实行封锁和限制政策。总之,大力发展以数控技术为核心的先进制造技术已成为世界各发达国家加速经济发展、提高综合国力和国家地位的重要途径。数控技术是用数字信息对机械运动和工作过程进行控制的技术,数控装备是以数控技术为代表的新技术对传统制造产业和新兴制造业的渗透形成的机电一体化产品,即所谓的数字化装备,其技术范围覆盖很多领域:(1)机械制造技术;(2)信息处理、加工、传输技术;(3)自动控制技术;(4)伺服驱动技术;(5)传感器技术;(6)软件技术等。
1NC Technology Trends
1 数控技术的发展趋势
NC technology applications not only bring about a revolutionary change to the traditional manufacturing industries, the manufacturing industry has become a symbol of industrialization. With the continuous development and application of numerical control technology fields expanded, and some important sectors of the national economy (IT. automobiles, light industry, health care, etc.) are playing an increasingly important role in the development. Because these businesses have modern digital equipment needed by the general trend of development. NC technology and equipment from the world's development trends, its main focus is the following :
    数控技术的应用不但给传统制造业带来了革命性的变化,使制造业成为工业化的象征,而且随着数控技术的不断发展和应用领域的扩大,他对国计民生的一些重要行业(IT、汽车、轻工、医疗等)的发展起着越来越重要的作用,因为这些行业所需装备的数字化已是现代发展的大趋势。从目前世界上数控技术及其装备发展的趋势来看,其主要研究热点有以下几个方面:
1.1 speed, the new trend of high-finishing technology and equipment
1.1高速、高精加工技术及装备的新趋势
Efficiency, and quality is the main advanced manufacturing technology. High-speed, high-finishing technologies can greatly enhance our efficiency, improve product quality and grades. shorten production cycles and improve their competitiveness on the market. Japan will end its tip technology as one of the five major modern manufacturing technology. International Institute of production (52th) will be identified as one of the Research Center for the 21st century. Recently, the overall use of a large aluminum alloy billets "emptied" the solution to the wing. large fuselage parts to a large number of parts to replace rivets, screws and other CONNECTIONS assembled. make component strength, stiffness and reliability improved. All of the processing equipment and high-speed, high-precision and high flexibility requirements. Hannover Expo from the case, the high speed processing centers will be to speed up stiffness, or even higher. operating speed of up to 100 m / min air around. Reliability and MTBF values abroad NC device has more than 6 copper, 30000h servo system MTBF value reached more than demonstrated very high reliability. In order to achieve high-speed, high-finishing, ancillary components such as the spindle, the rapid development of a linear motor, Applications will continue to expand.
    效率、质量是先进制造技术的主体。高速、高精加工技术可极大地提高效率,提高产品的质量和档次,缩短生产周期和提高市场竞争能力。为此日本先端技术研究会将其列为5大现代制造技术之一,国际生产工程学会(CIRP)将其确定为21世纪的中心研究方向之一。近来采用大型整体铝合金坯料“掏空”的方法来制造机翼、机身等大型零件来替代多个零件通过众多的铆钉、螺钉和其他联结方式拼装,使构件的强度、刚度和可靠性得到提高。这些都对加工装备提出了高速、高精和高柔性的要求。从EMO2001展会情况来看,高速加工中心进给速度可达80m/min,甚至更高,空运行速度可达100m/min左右。在可靠性方面,国外数控装置的MTBF值已达6 000h以上,伺服系统的MTBF值达到30000h以上,表现出非常高的可靠性。 为了实现高速、高精加工,与之配套的功能部件如电主轴、直线电机得到了快速的发展,应用领域进一步扩大。
