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.

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。

Reading Target
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。

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
