摘要

当今世界各国制造业广泛采用数控技术，以提高制造能力和水平，提高对动态多变市场的适应能力和竞争能力。此外世界上各工业发达国家还将数控技术及数控装备列为国家的战略物资，不仅采取重大措施来发展自己的数控技术及其产业，而且在“高精尖”数控关键技术和装备方面对我国实行封锁和限制政策。总之，大力发展以数控技术为核心的先进制造技术已成为世界各发达国家加速经济发展、提高综合国力和国家地位的重要途径。

装备工业的技术水平和现代化程度决定着整个国民经济的水平和现代化程度，数控技术及装备是发展新兴高新技术产业和尖端工业的使能技术和最基本的装备。马克思曾经说过“各种经济时代的区别，不在于生产什么，而在于怎样生产，用什么劳动资料生产”。制造技术和装备就是人类生产活动的最基本的生产资料，而数控技术又是当今先进制造技术和装备最核心的技术。

数控技术是用数字信息对机械运动和工作过程进行控制的技术，数控装备是以数控技术为代表的新技术对传统制造产业和新兴制造业的渗透形成的机电一体化产品，即所谓的数字化装备，其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)传感器技术；(6)软件技术等。

数控技术的应用不但给传统制造业带来了革命性的变化，使制造业成为工业化的象征，而且随着数控技术的不断发展和应用领域的扩大，他对国计民生的一些重要行业的发展起着越来越重要的作用，因为这些行业所需装备的数字化已是现代发展的大趋势。

作为一名在校学生，积极地投身实践争做社会主义的创造着与建设者是我义不容辞的责任。而零件又是组成各种复杂机械的根本，所以我坚信用自己所学为国家、社会做出应有的贡献。
