Numerical control may be defined as a method of accurately managing the movement of machine tools by a series of programmed numerical data which activate the motors of the machine tool.There is nothing complex or magical about this system.It is based on the simple fundamental that combines automatic measurement of machine table slide will move with series of programmed instructions.The numerically controlled machine is supplied with detailed information regarding the part by means of punched tape.The machine decodes this punched information and electronic devices activate the various motors on the machine tool,causing them to position the work and follow specific machining instructions.The measuring and recording devious incorporated into numerically controlled machine tools assure that the part being manufactured will be accurate .Numerically controlled machines minimize the possibility of human error which existed before there development.Over recent years,they have been great improvements to NC system.In many cases,the tape reader on NC machines is bypassed and the machine receives its instructions directly from a computer.However the student should be made aware of the basics of NC before being exposed to the more recent developments of computerized numerical control(CNC) and direct numerical control(DNC).

数值控制可以被定义为一种精确控制机床运动的一系列程序的数字数据,驱动机床电机的.并不是很复杂系统.它是基于简单的基础,结合机床滑台的自动测量,将与一系列程序指令.数控机床是提供有关的详细信息部分利用打孔纸带.该机解码本打孔信息和电子设备激活各种机床上的电动机,使他们的位置,和之后的特殊加工指令.测量和记录的狡猾的数控机床中保证该部分制造将是准确的.数控机床减少人为错误的可能性存在,才有发展.近年来,他们已经有了很大的改进,数控系统.在许多情况下,磁带读者对数控机床是绕过和机接收指令直接从电脑.然而,学生应了解数控的基础才接触到更多的最新发展的计算机数值控制（数控）和直接数字控制（数控）.
