文档介绍：摘要
数字控制是近代发展起来的一种自动化控制技术是用数字化信号对机床运动极其加工过程进行控制的一种方法,随着科学技术的迅猛发展,数控机床已经是一个的重要标准。
数控机床是装有程序控制系统的机床。该系统能够逻辑地处理具有使用号码,或其他符号编码指令规定的程序。
数控机床是以数控技术为代表的新技术对传统制造产业的渗透形成的机电一体化产品,起技术范围覆盖很多领域:(1)机械制造技术(2)信息处理、加工、传输技术;(3)自动控制技术;(4)伺服驱动技术;(5)传感技术;(6软件技术等。计算机对传统机械业的渗透,完全改变了制造业。制造业不但成为工业化的象征,而且由于信息技术的渗透,使制造业犹如朝阳产业,具有广阔的发展天地。
数控机床就是将加工过程所需的各种步骤以及刀具与工件之间的相对位移量都是用数字化的代码来表示。通过控制介质数字信息送入专用区域通用的计算机。计算机对输入的信息进行处理,发出各种指令来控制机床的伺服系统或其他执行元件,使机床自动加工出所需要的工件。

Abstract
Digital control is a kind of automatic control technology developed in recent years is a method of using the digital signals of the machine is the machining process control, with the rapid development of science and technology, numerical control machine tool is an important standard of mechanical industry of a country level.
NC machine tool is provided with the program control system of machine tool. The system can be logically processing with the use of numbers, or other symbols coded instructions procedures.
NC machine tool is the ration of the new technology of numerical control technology as the representative of the traditional manufacturing industries form the integration of mechanical and electrical products, technical scope covers many fields: (1) mechanical manufacturing technology (2) information processing, processing, transmission technology; (3) the automatic control technology; (4) servo drive technology; (5) sensor technology; (6 software technology. puter ration of the traditional mechanical industry, completely changed the manufacturing industry. The manufacturing industry is not only to e a symbol of industrialization, and because the ration of information technology, the manufacturing industry is a sunrise industry, has the broad development world.
NC machine tools is the relative displacement between the various steps required to process as well as the tool and workpiece are using digital codes to represent. By controlling the medium of digital information into the special
