1、机床数控改造外文翻译 外文翻译机床数控改造_Machine tool numerical control reformsFirst, CNC systems and the development trend of history一、数控系统发展简史及趋势1946 birth of the worlds first electronic computer, which shows that human beings created to enhance and replace some of the mental work tools. It and human agriculture, in
2、dustrial society in the creation of those who merely increase compared to manual tools, from a qualitative leap for mankinds entry into the information society laid the foundation. Six years later, in 1952, computer technology applied to the machine in the United States was born first CNC machine to
3、ols. Since then, the traditional machine produced a qualitative change. Nearly half a century since the CNC system has experienced two phases and six generations of development. 1946年诞生了世界上第一台电子计算机，这表明人类创造了可增强和部分代替脑力劳动的工具。它与人类在农业、工业社会中创造的那些只是增强体力劳动的工具相比，起了质的飞跃，为人类进入信息社会奠定了基础。6年后，即在1952年，计算机技术应用到了机床上
4、，在美国诞生了第一台数控机床。从此，传统机床产生了质的变化。近半个世纪以来，数控系统经历了两个阶段和六代的发展。1.1, Numerical Control NC phase 1952 to 1970 1.1、数控（NC）阶段（19521970年）Early computers computational speed low and the prevailing scientific computing and data processing is not affected, but can not meet the requirements of real-time control mach
5、ine. People have to use digital logic circuit tied into a single machine as a dedicated computer numerical control system, known as the hardware connection NC HARD-WIRED NC , called the Numerical Control NC . With the development of components of this phase after three generations, that is, in 1952
6、the first generation - tube; 1959 of the second generation - transistor; 1965 of the third generation - small-scale integrated circuits.早期计算机的运算速度低，对当时的科学计算和数据处理影响还不大，但不能适应机床实时控制的要求。人们不得不采用数字逻辑电路搭成一台机床专用计算机作为数控系统，被称为硬件连接数控（HARD-WIRED NC），简称为数控（NC）。随着元器件的发展，这个阶段历经了三代，即1952年的第一代-电子管；1959年的第二代-晶体管；1965
7、年的第三代-小规模集成电路。1.2, Computer Numerical Control CNC phase 1970 to present 1.2、计算机数控（CNC）阶段（1970年现在）To 1970, GM has been a small computer and mass-produced. So it transplant system as the core component of NC, have entered a Computer Numerical Control CNC stage in front of the computer should be univer
8、sal word omitted . To 1971, the United States INTEL company in the world will be the first time the two most core computer components - computing and controller, a large-scale integrated circuit technology integration in a chip, called the microprocessor MICROPROCESSOR , also known as the central pr
9、ocessing unit CPU .到1970年，通用小型计算机业已出现并成批生产。于是将它移植过来作为数控系统的核心部件，从此进入了计算机数控（CNC）阶段（把计算机前面应有的通用两个字省略了）。到1971年，美国INTEL公司在世界上第一次将计算机的两个最核心的部件-运算器和控制器，采用大规模集成电路技术集成在一块芯片上，称之为微处理器（MICROPROCESSOR），又可称为中央处理单元（简称CPU）。1974 microprocessor to be used in CNC system. This is because the function of the computer is

Minicomputer reliability and then not ideal. Early microprocessor speed and functionality while still not high en
11、ough, but can be adopted to solve the multi-processor architecture. As microprocessor core is a general computer components, it is still known as the CNC.到1974年微处理器被应用于数控系统。这是因为小型计算机功能太强，控制一台机床能力有富裕（故当时曾用于控制多台机床，称之为群控），不如采用微处理器经济合理。而且当时的小型机可靠性也不理想。早期的微处理器速度和功能虽还不够高，但可以通过多处理器结构来解决。由于微处理器是通用计算机的核心部件，故
12、仍称为计算机数控。By 1990, PC machines personal computers, domestic habits that computer performance has been developed to a high stage, as a CNC system to meet the requirements of the core components. NC system based on PC has now entered the stage.到了1990年，PC机（个人计算机，国内习惯称微机）的性能已发展到很高的阶段，可以满足作为数控系统核心部件的要求。数控
13、系统从此进入了基于PC的阶段。In short, CNC has also experienced a stage three generations. That is, in 1970s fourth generation - small computer; 1974 of the fifth generation - microprocessors and the sixth-generation 1990 - Based on the PC called PC-BASED abroad .总之，计算机数控阶段也经历了三代。即1970年的第四代-小型计算机；1974年的第五代-微处理器和1
14、990年的第六代-基于PC（国外称为PC-BASED）。Also pointed out that, although the foreign computer has been renamed NC CNC , but China still customary said Numerical Control NC . Therefore, we stress theday-to-day NC, in essence, is that computer numerically controlled.还要指出的是，虽然国外早已改称为计算机数控（即CNC）了，而我国仍习惯称数控（NC）。所以我们日
15、常讲的数控，实质上已是指计算机数控了。1.3, the trend of future development of NC1.3、数控未来发展的趋势1.3.1 continue to open, the sixth generation of PC-based development1.3.1继续向开放式、基于PC的第六代方向发展 Based on the PC with the open, low-cost, high reliability, rich in resources such as hardware and software features, and more CNC sys

17、tem. Remote communications, remote diagnostics and maintenance will be more widespread.基于PC所具有的开放性、低成本、高可靠性、软硬件资源丰富等特点，更多的数控系统生产厂家会走上这条道路。至少采用PC机作为它的前端机，来处理人机界面、编程、联网通信等问题，由原有的系统承担数控的任务。PC机所具有的友好的人机界面，将普及到所有的数控系统。远程通讯，远程诊断和维修将更加普遍。1.3.2 high-speed and high-precision Development1.3.2向高速化和高精度化发展This i

23、udes computer power.从微观上看，数控机床比传统机床有以下突出的优越性，而且这些优越性均来自数控系统所包含的计算机的威力。2.1.1 can be processed by conventional machining is not the curve, surface and other complex parts2.1.1 可以加工出传统机床加工不出来的曲线、曲面等复杂的零件。Because computers are superb computing power can be accurately calculated instantaneous each coordi
24、nate axis movement exercise should be instantaneous, it can compound into complex curves and surfaces.由于计算机有高超的运算能力，可以瞬时准确地计算出每个坐标轴瞬时应该运动的运动量，因此可以复合成复杂的曲线或曲面。2.1.2 automated processing can be achieved, but also flexible automation to increase machine efficiency than traditional 3 to 7 times.2.1.2 可以
25、实现加工的自动化，而且是柔性自动化，从而效率可比传统机床提高37倍。Because computers are memory and storage capacity, can be imported and stored procedures remember down, and then click procedural requirements to implement the order automatically to achieve automation. CNC machine tool as a replacement procedures, we can achieve an
26、other work piece machining automation, so that single pieces and small batch production can be automated, it has been called flexible automation.由于计算机有记忆和存储能力，可以将输入的程序记住和存储下来，然后按程序规定的顺序自动去执行，从而实现自动化。数控机床只要更换一个程序，就可实现另一工件加工的自动化，从而使单件和小批生产得以自动化，故被称为实现了柔性自动化。2.1.3 high precision machining parts, the si

30、gh. In addition, CNC machine tools or the FMC Flexible Manufacturing Cell , FMS flexible manufacturing system and CIMS Computer Integrated Manufacturing System , and other enterprises, the basis of information transformation. NC manufacturing automation technology has become the core technology and
31、basic technology.以上这些优越性是前人想象不到的，是一个极为重大的突破。此外，机床数控化还是推行FMC（柔性制造单元）、FMS（柔性制造系统）以及CIMS（计算机集成制造系统）等企业信息化改造的基础。数控技术已经成为制造业自动化的核心技术和基础技术。 2.2, the macro view of the necessity 2.2、宏观看改造的必要性From a macro perspective, the military industrial developed countries, the machinery industry, in the late 1970s, ea
32、rly 1980s, has begun a large-scale application of CNC machine tools. Its essence is the use of information technology on the traditional industries including the military, the Machinery Industry for technological transformation. In addition to the manufacturing process used in CNC machine tools, FMC
33、, FMS, but also included in the product development in the implementation of CAD, CAE, CAM, virtual manufacturing and production management in the implementation of the MIS Management Information System , CIMS, and so on. And the products that they produce an increase in information technology, incl
34、uding artificial intelligence and other content. As the use of information technology to foreign forces, the depth of Machinery Industry referred to as information technology , and ultimately makes their products in the international military and civilian products on the market competitiveness of mu
35、ch stronger. And we in the information technology to transformtraditional industries than about 20 years behind developed countries. Such as possession of machine tools in China, the proportion of CNC machine tools CNC rate in 1995 to only 1.9 percent, while Japan in 1994 reached 20.8 percent, every
36、 year a large number of imports of mechanical and electrical products. This also explains the macro CNC transformation of the need.从宏观上看，工业发达国家的军、民机械工业，在70年代末、80年代初已开始大规模应用数控机床。其本质是，采用信息技术对传统产业（包括军、民机械工业）进行技术改造。除在制造过程中采用数控机床、FMC、FMS外，还包括在产品开发中推行CAD、CAE、CAM、虚拟制造以及在生产管理中推行MIS（管理信息系统）、CIMS等等。以及在其生产的产品中
37、增加信息技术，包括人工智能等的含量。由于采用信息技术对国外军、民机械工业进行深入改造（称之为信息化），最终使得他们的产品在国际军品和民品的市场上竞争力大为增强。而我们在信息技术改造传统产业方面比发达国家约落后20年。如我国机床拥有量中，数控机床的比重（数控化率）到1995年只有1.9，而日本在1994年已达20.8，因此每年都有大量机电产品进口。这也就从宏观上说明了机床数控化改造的必要性。Third, CNC machine tools and production lines of the transformation of the market 三、机床与生产线数控化改造的市场3.1, C
38、NC transformation of the market 3.1、机床数控化改造的市场My current machine total more than 380 million units, of which only the total number of CNC machine tool 113,400 Taiwan, or that Chinas CNC rate of less than 3 percent. Over the past 10 years, Chinas annual output of about 0.6 CNC machine tools to 0.8 mi
39、llion units, an annual output value of about 1.8 billion yuan. CNC machine tools annual rate of 6 per cent. Chinas machine tool easements over age 10 account for more than 60% below the 10 machines, automatic / semi-automatic machine less than 20 per cent, FMC / FMS, such as a handful more automated
40、 production line the United States and Japan automatic and semi-automatic machine, 60 percent above . This shows that we the majority of manufacturing industries and enterprises of the production, processing equipment is the great majority of traditional machine tools, and more than half of military
41、 age is over 10 years old machine. Processing equipment used by the prevalence of poor quality products, less variety, low-grade, high cost, supply a long period, in view of the international and domestic markets, lack of competitiveness, and a direct impact on a companys products, markets, efficien
42、cy and impact The survival and development of enterprises. Therefore, we must vigorously raise the rate of CNC machine tools. 我国目前机床总量380余万台，而其中数控机床总数只有11.34万台，即我国机床数控化率不到3。近10年来，我国数控机床年产量约为0.60.8万台，年产值约为18亿元。机床的年产量数控化率为6。我国机床役龄10年以上的占60以上；10年以下的机床中，自动/半自动机床不到20，FMC/FMS等自动化生产线更屈指可数（美国和日本自动和半自动机床占60以
43、上）。可见我们的大多数制造行业和企业的生产、加工装备绝大数是传统的机床，而且半数以上是役龄在10年以上的旧机床。用这种装备加工出来的产品普遍存在质量差、品种少、档次低、成本高、供货期长，从而在国际、国内市场上缺乏竞争力，直接影响一个企业的产品、市场、效益，影响企业的生存和发展。所以必须大力提高机床的数控化率。3.2, import equipment and production lines of the transformation of NC market 3.2、进口设备和生产线的数控化改造市场Since Chinas reform and opening up, many foreig
44、n enterprises from the introduction of technology, equipment and production lines for technological transformation. According to incomplete statistics, from 1979 to 1988 10, the introduction of technological transformation projects are 18,446, about 16.58 billion US dollars. 我国自改革开放以来，很多企业从国外引进技术、设备
45、和生产线进行技术改造。据不完全统计，从19791988年10年间，全国引进技术改造项目就有18446项，大约165.8亿美元。These projects, the majority of projects in Chinas economic construction play a due role. Some, however, the introduction of projects due to various reasons, not equipment or normal operation of the production line, and even paralyzed, a
46、nd the effectiveness of enterprises affected by serious enterprise is in trouble. Some of the equipment, production lines introduced from abroad, the digestion and absorption of some bad, spare parts incomplete, improper maintenance, poor operating results; only pay attention to the introduction of
47、some imported the equipment, apparatus, production lines, ignore software, technology, and management, resulting in items integrity, and potential equipment can not play, but some can not even start running, did not play due role, but some production lines to sell the products very well, but not bec
48、ause of equipment failure production standards; because some high energy consumption, low pass rate products incur losses, but some have introduced a longer time, and the need for technological upgrading. Some of the causes of the equipment did not create wealth, but consumption of wealth. 这些项目中，大部分项目为我国的经济建设发挥了应有的作用。但是有的引进项目由于种种原因，设备或生产线不能正常运转，甚至瘫痪，使企业的效益受到影响，严重的使企业陷入困境。一些设备、生产线从国外引进以后，有的消化吸收不好，备件不全，维护不当，结果运转不良；有的引进时只注意引进设备、仪器、生产线，忽视软件、工艺、管理等，造成项目不完整，设备潜力不能发挥；有的甚至不能启动运行，没有发挥应有的作用；有的生产线的产品销路很好，但是因为设备故障不能达产达标；有的因为能耗高、产品合格率低而造成亏损；有的已引进较长时间，需要进行技术更新。种种原因使有的设备不仅没有创造财富，反而消耗着财
