应老师要求，要交一篇300单词以上的数控机床介绍，种类不限，什么都可以，只要是数控机床。中文英文都要，翻译软件或网站翻译的不要！谢谢大家了速度！速度！速度！
怪我的问题提的不清楚，误导大家了不好意思。是要某数控机床的说明，就是说不是数控机床这种物体的说明，而是要某型号机床的说明.....什么型号的都可以。只要具体到某型号就可以了，大概的说明就好。谢谢大家！
已经很对口了，还要翻译，你应该很满意了。不要辜负我的好心哦。
Numerical control or numerically controlled (NC) machine tools are machines that are automatically operated by commands encoded on a digital medium.
数控（NC）机床是自动运作的机器，它依靠在数字媒质上加以编码的指令工作。NC machines were first developed soon after World War II and made it possible for large quantities of the desired components to be very precisely and efficiently produced (machined) in a reliable repetitive manner.数控机床最早在第二次世界大战后不久开发成功，这使得大量的所需零件能以可靠而可重复的方式很精密又高效地生产（加工）出来。 These early machines were often fed instructions which were punched onto paper tape or Hollerith cards, although Mylar (or polyester) tapes became popular because of their high durability and quality. 这些早期的机床往往要馈送进在纸带或何累内斯卡上打孔的指令，不过Mylar(或称为聚酯）带因为具有高的耐用性和质量已经非常普及。In the 1960s, NC machines largely gave way to CNC, or computer numerical control, machines. (GE had its NC 550 workhorse for many years until they came out with their first CNC (model 1050) in August 1974.)在20世纪60年代，数控机床在很大程度上让位于计算机数字控制（CNC）的机床。（通用电气公司（GE）拥有自己的NC550型重工作负荷机床很多年，直至他们在1974年8月展示自己第一台CNC机床为止（1050型））。
Numerical Control (NC) was the forerunner of today's Computer Numerical Control (CNC), which controls the automation of machine tools and the inherent tool processes for which they are designed.数字控制（NC）是今天的计算机数字控制（CNC）的先驱，它控制机床的自动化以及被设计的内在加工过程。 The CNC machine tool is the servo actuator of the CAD/CAM (Computer Assisted Design/Computer Assisted Manufacturing) technology both literally and figuratively. CNC机床是CAD/CAM（计算机辅助设计和计算机辅助制造）技术的逐字逐图的伺服操作机构。CNC inherits from NC the essential character of by-the-numbers interpolation of transition points in the work envelope of a multi-axis motion platform, based on the separation of programming from operations. CNC从NC继承了基本的特点，即据于编程与操作分离，在多轴移动平台的工件包络线的过渡点按数字译码。The set of instructions, or "program" (usually an ASCII text file in which, in its simplest form, a line of text specifies the axial coordinates of a point in the work envelope) is prepared from a blueprint or CAD file and transferred to the memory of the CNC via floppy drive, serial data interface or a network connection. 指令集或“程序”（通常是一个ASCII文本文件，其中以其最简单的形式，一行文本规定工件包络线上一点的轴坐标）由设计图或CAD文件制作，并通过软盘驱动器、串行数据接口或网络连接，被传送到CNC的存储器中。Once stored in the CNC memory and selected, the program is executed by pressing the appropriate key on the machine operator panel.一旦存储在CNC存储器中并经过选择，该程序就可通过按机床操作面板上适当的键而加以执行。

只能帮你找到英文的了，中文自己搞定吧。
The abbreviation CNC stands for computer numerical control, and refers specifically to a computer "controller" that reads G-code instructions and drives a machine tool, a powered mechanical device typically used to fabricate components by the selective removal of material. CNC does numerically directed interpolation of a cutting tool in the work envelope of a machine. The operating parameters of the CNC can be altered via a software load program.
A series of CNC machines may be combined into one station, commonly called a "cell", to progressively machine a part requiring several operations. CNC machines today are controlled directly from files created by CAM software packages, so that a part or assembly can go directly from design to manufacturing without the need of producing a drafted paper drawing of the manufactured component. In a sense, the CNC machines represent a special segment of industrial robot systems, as they are programmable to perform many kinds of machining operations (within their designed physical limits, like other robotic systems). CNC machines can run over night and over weekends without operator intervention. Error detection features have been developed, giving CNC machines the ability to call the operator's mobile phone if it detects that a tool has broken. While the machine is awaiting replacement on the tool, it would run other parts it is already loaded with up to that tool and wait for the operator. The ever changing intelligence of CNC controllers has dramatically increased job shop cell production. Some machines might even make 1000 parts on a weekend with no operator, checking each part with lasers and sensors.
