7、 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。此外世界上各工业兴旺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开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, 大力开展以数控技术为核心的先进制造技术已成为世界各兴旺国家加速经济发 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
8、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。NC Technology Trends1数控技术的开展趋势NC technology applications not only bring about a revolutionary change to the traditional manufacturing industries, the manufacturing industry has become a symbol of industr
9、ialization. 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
10、 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开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)的开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开展的大趋
11、势o从目前世界上数控技术及其装 备开展的趋势来看,其主要研究热点有以下几个方面:speed, the new trend of high-finishing technology and equipment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
12、, 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 o
13、verall 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-
14、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 va
15、lue 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
16、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钾钉、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EM02001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 OOOh以上,伺服系统的MTBF值到达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
17、主轴、 直线电机得到了快速的开展,应用领域进一步扩大。5-axis machining machine tool and the rapid development25轴联动加工和复合加工机床快速开展Using 5-axis machining of 3D components, the best available tool for cutting geometry not only finish high, but also greatly increase efficiency. Generally believed that one 5-axis machine efficiency
18、can mean 2, 3-axis machine tools, particularly the use of cubic boron nitride and other superhard materials for high-speed milling of hardened steel cutter parts, 5-axis machining for more than three-ax is machining efficiency. But for the past five-axis CNC system mainframe complex reasons, their p
19、rices several times higher than the 3-axis CNC machine tools, plus programming techniques rather difficult, constraining the development of a five-axis machine tools. At present, due to a spindle, enabling 5-axis machining spindle head of composite structures simplified, manufacturing difficulties a
20、nd costs lowered significantly, reducing the gap between the price of CNC system. So for the first type of compound axis and 5-axis machine machine tool (including five surface Machine) development. In Hannover Expo, the new machine in Japan for the first 5 axis surface machining machine compound, f
21、our vertical plane processing can be realized and arbitrary angle processing, 5 5-axis machining and surface processing makes on the same machine can be achieved, but also to achieve the processing of tilted surface and inverted cone hole. German companies DMG display DMUVbution series processing ce
22、nter under 5 fixture in a five-axis machining and surface processing, CAM or CNC control system can be controlled, directly or indirectly.采用5轴联动对三维曲面零件的加工,可用刀具最正确几何形状进行切削,不 仅光洁度高,而且效率也大幅度提高。一般认为,1台5轴联动机床的效率可以 等于2台3轴联动机床,特别是使用立方氮化硼等超硬材料铳刀进行高速铳削淬 硬钢零件时,5轴联动加工可比3轴联动加工发挥更高的效益。但过去因5轴联 动数控系统、主机结构复杂等原因,其价格
23、要比3轴联动数控机床高出数倍,加 之编程技术难度较大,制约了 5轴联动机床的开展。当前由于电主轴的出现, 使得实现5轴联动加工的复合主轴头结构大为简化,其制造难度和本钱大幅度降 低,数控系统的价格差距缩小。因此促进了复合主轴头类型5轴联动机床和复合 加工机床(含5面加工机床)的开展。在EM02001展会上,新日本工机的5面 加工机床采用复合主轴头,可实现4个垂直平面的加工和任意角度的加工,使得 5面加工和5轴加工可在同一台机床上实现,还可实现倾斜面和倒锥孔的加工。 德国DMG公司展出DMUVoution系列加工中心,可在一次装夹下5面加工和5轴 联动加工,可由CNC系统控制或CAD/CAM直接

37、 industries estimate2对我国数控技术及其产业开展的基本估计NC Technology started in 1958, nearly 50 years of development history can be divided into three stages : The first stage was from 1958 to 1979, closed development stage. At this stage, as foreign technology blockade, and our basic conditions, the development of
38、 NC relatively slow. The second stage is the June 5H, Plan and during the Eighth Five-year Plan/* a period that the introduction of technology, absorbing system made preliminary stage. At this stage, due to the importance of reform and opening up and national and international research and developme
