Machines may be programmed manually or with the aid of a computer. Manual prart programming; programming done by a computer is called computer aided programming (CAP). 机床可以手工编程或在计算机的帮助下编程。手工编程是 由人工完成的，而计算机辅助编程（CAP）是通过计算机完 成的. Sometimes a manual program is entered into the machine’s controller via its own keypad. This is known as manual data input (MDI). This text will focus on manual part programming. 还有大家熟知的手动数据输入方式（MDI），它是通过其 自带键盘，将程序输入到机床的控制器。本课将重点讲述手 工编程。

数控技术专业英语
二、重难点句 • Servo controls can be any group of electrical, hydraulic, or pneumatic devices which are used to control the position of machine tool slides. • In the open-loop system, the tape is fed into a tape reader which decodes the information punched on the tape and stores it briefly until the machine is ready to use it. The tape reader then converts the information into electrical pulses or signals. These signals are sent to the control unit, which energizes the servo control units. The servo control units direct the servomotors to perform certain functions according to the information supplied by the tape. The amount each servomotor will move depends upon the number of electrical pulses it receives from the servo control unit. • The closed-loop system is similar to the open-loop system with the exception that a feedback unit is introduced into the electrical circuit. This feedback unit, often called a transducer, compares the amount the machine table has been moved by the servomotor with the signal sent by the control unit. The control unit instructs the servomotor to make whatever adjustments are necessary until both the signal from the control unit and the one from the servo unit are equal.

They can be played back，edited，and processed by the controller．All programs resided in RAM，however， are lost when the CNC machine is turned off．These programs can be saved on auxiliary storage devices such as punched tape，magnetic tape，or magnetic disk. The MCU units have graphics screens that can display not only the CNC program but also the cutter paths generated and any errors in the program.
NC technology has found many applications, including lathes, and turning centers, milling machines and machining centers, punches, electrical discharge machines (EDM), flame cutters, grinders, and testing and inspection equipments. The most complex CNC machine tools are the turning center with a ten-station turret that accepts quick-change tools, the vertical machining center that the tool magazine is on the left of the machine and horizontal machining center equipped with an automatic tool changer, shown in Figure 1-1 and Figure 1-2 respectively. Generally speaking, tool magazines can store 200 cutting tools.

For U bending (channel bending) pressures will be approximately twice those required for V bending，edge bending ， requires about one-half those needed for V bending. Springback in that all materials have a finite modulus of elasticity, plastic deformation is followed, when bending pressure on metal is removed, by some elastic recovery (see Figure 2-15) .

高等职业技术学院数控专业英语教学改革的研究
高等职业技术学院数控专业英语教学改革的研究摘要数控专业英语是高等院校数控专业的必修课。
本文针对高等职业技术学院数控英语的教学现状，从师资队伍、教材、教学方法及教学手段方面提出了教学改革的几点措施。
关键词高等职业技术学院数控专业英语教学改革随着社会的发展，各行业对复合型人才要求有所提高。
随着我国制造加工业越来越多的从国外引进新技术、新设备，只有培养出具备一定外语水平和专业技术的复合型人才才能满足社会的需要。
因此，高职数控专业学生学好专业英语非常有意义。
目前大多数高职院校都设有专业英语课程，但教学效果并不是太理想。
现结合高职数控专业英语教学现状，提出了几点教学改革的措施，总结如下：一、数控专业英语教学现状（一）教师方面。
数控专业英语是以英语为基础又与数控专业相结合的课程，要求授课老师具备数控专业方面的知识，因此现在大多数高职院校的这门课程一般由专业老师授课。
这些专业老师有足够的专业知识，但英语口语表达能力比较差，不熟悉英语教学法，课堂上大部分是用中文表达，课堂效果不是很好，专业英语课的开设状况令人担忧。
（二）学生方面。
首先高职院校的学生文化基础差，底子薄，特别是对于理工科学生，英语更是一大难题。
他们的英语基础较差，词汇量小，语法知识掌握不够，阅读、分析能力差，相当一部分人对英语学习存在抵触情绪；其次，一些学生认为毕业后做技术工人，学专业英语没有什么用，加上专业英语涉及的专业知识较多，内容枯燥，句型复杂，语法太多，初学者学习起来有难度，这会打击学生学习的积极性，个别同学会出现厌学、逃课等情况；最后，由于一些院校把专业英语安排在第三学期，这时的学生刚开始接触专业知识，对专业知识了解不够，加上专业英语课时也较少，这更增加了学生学习专业英语的难度。
（三）教材及教学方法。
在数控专业英语的教学中，老师普遍感觉很难找到一本适合大纲要求的教材。
有些教材介绍的数控机器和设备已经过时，有些教材介绍的内容又过于深奥，复杂长句较多，学生难于理解，同时也不利于授课老师的讲解。
数控技术 专业 英语
数控技术专业英语With the rapid development of manufacturing technology, the demand for CNC (Computer Numerical Control) professionals has been increasing steadily. The application of CNC technology is becoming increasingly widespread, and CNC programming has become an essential part for the manufacturing industry. When it comes to the study of CNC technology, professionals must master the relevant technical vocabulary in English, as it is often used as the adaptation language in the field. Therefore, it is imperative to learn CNC-related terminology in English, especially for those who specialize in this field.The study of CNC technology in English covers a broad range of topics. In this article, we will narrow our focus to the following areas:1. Introduction to CNC TechnologyCNC technology is the process of using computers to automate machine tools. The CNC machine tool cuts or carves away material from raw stocks to create a finished product.It is used in a variety of industries, including aerospace, automotive, precision engineering and medical devices. Before understanding CNC technology and its applications, it is necessary to understand basic CNC terminology such as axis, coordinates, program, tool path, and so on.2. CNC ProgrammingProgramming is an essential part of CNC technology. A fundamental understanding of the syntax, parameters, and syntax used to create CNC programs is vital. CNC programs aregenerally written in G-code, which is a form of machine code that a CNC machine tool can understand. The CNC programs are used to direct the CNC machine tool for cutting or carving actions.3. CNC Machining CentersCNC machining centers are automated machine tools that can perform complex machining operations. Machining operations include drilling, milling, grinding, and turning.A CNC machining center employs a variety of tools such as drills, saws, and lathes to perform various tasks. A skilled CNC operator must have a comprehensive knowledge of the various types of CNC machining centers and an in-depth understanding of the proper application of such centers.4. Industrial Robotics in CNC TechnologyIndustrial robots are revolutionizing CNC technology. They are used in CNC manufacturing to perform repetitive tasks quickly and accurately. Industrial robots are used in various CNC operations such as deburring, welding, drilling, and painting. It is important to understand the programming and functionality of the robots to ensure efficient and safe operations.In conclusion, CNC technology is a vast and exciting field that requires a sound understanding of technical vocabulary. However, mastering the English language is essential for professionals specializing in CNC technology. With this knowledge, professionals will gain a higher level of competency, perform their responsibilities effectively and expand their career opportunities in this fast-growing industry.。

Address An address is a letter that describes the meaning of the numerical value following the address. For example, the G in the codes G00 and the X in the codes X-3.75. 地址 地址是用于描述其后数值意义的一个字母。例如， 代码G00中的G和代码X-3.75中的X（都是地址）。

Word
Characters are used to form words. Program words are composed of two main parts: an address followed by a number. Words are used to describe such important information as machine motions and dimensions in programs. 程序字 程序字由字符组成，它主要由两部分组成：地址 及紧随其后的数字。程序字用于描述程序中机床的运 动和尺寸等重要信息。

After
reading this unit, you should be able to understand the format of CNC program.
Hale Waihona Puke TextA CNC program is composed of a series of sequential instructions related to the machining of a part. Each instruction is specified in a format the CNC system can accept, interpret and process. Various controls have a different format, The format to be used in this text is known as the word address. It was originally developed for use with NC tapes and has been retained for CNC programming. CNC程序由一系列与加工零件相关的连续指令构 成。程序中的每个指令都遵循特定的格式， CNC系 统接受、编译并执行这种格式。不同控制系统采用的 格式不同，本文中将介绍字地址编程格式。最初，它 是为了和数控纸带配套使用而开发出来的，CNC将该 编程方式保留了下来。

Block
A block is a complete line of information to the CNC machine. It is composed of one word or an arrangement of words. Blocks may vary in length. Thus, the programmer need only include in a block those words required to execute a particular machine function. 程序段 对于CNC机床来说，一个程序段就是一条完整的 信息，它由一个或多个程序字组成。程序段可长可短， 因此，要执行特定的机床功能，程序员只要在程序段 中写入需要的字即可。
Text
The word address format is based on a combination of one letter and one or more digits, see Figure 8-1. The word address refers to a specific register of the control memory. Some typical words are: G01 M30 D25 X5.75 N105 HOI YO S2500 Z-5.14 F12.0 T0505 T05 /M01 B180.0 字地址格式基于单个字母和一个或多个数字的结合。 请参考图8-1.一个字地址就是指控制器的内存中一个特 定的寄存器。一些典型的字如下： G01 M30 D25 X5.75 N105 HOI YO S2500 Z-5.14 F12.0 T0505 T05 /M01 B180.0
