内容摘要：数控技术及数控装备已成为关系国家战略和体现国家综合实力水平的重要基础性产业，其水平高低是衡量一个国家制造业现代化程度的核新标志。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。数控技术是现代制造业实现自动化、柔性化、集成化生产的基础，离开了数控技术，先进制造技术就成了无本之木。
Abstaract：Numerical control technology and numerical control equipment has become a national strategy relationship and reflect the national comprehensive strength level of important basic industry, it’s levei is the measure of a country manufacturing modernization degree of nuclear new mark.Not only the numerical control technology application for the traditional manufacturing industry has brought the revolutionary change, causes the manufacturing industry to become the industrialization the symbol. Numerical control technology is the modern manufacturing automation, flexibility, integration production base, left the numerical control technology, advanced manufacturing technology became like.
