数控技术的发展趋势
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（IT、汽车、轻工、医疗等）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。从目前世界上数控技术及其装备发展的趋势来看，其主要研究热点有以下几个方面［1～4］。
1.1高速、高精加工技术及装备的新趋势
效率、质量是先进制造技术的主体。高速、高精加工技术可极大地提高效率，提高产品的质量和档次，缩短生产周期和提高市场竞争能力。为此日本先端技术研究会将其列为5大现代制造技术之一，国际生产工程学会（CIRP）将其确定为21世纪的中心研究方向之一。
Development trend of a
numerical control technology
The application of numerical control technology has not only brought the revolutionary change to manufacturing industry of the tradition, make the manufacturing industry become the industrialized symbol , and with the constant development of numerical control technology and enlargement of the application, the development of some important trades (IT , automobile , light industry , medical treatment ,etc. ) to the national economy and the people''s livelihood of his plays a more and more important role, because the digitization that these trades needed to equip has already been the main trend of modern development. Numerical control technology in the world at present and equiping the development trend to see, there is the following several respect [1- ] in its main research focus .
1.A high-speed , high finish machining technology and new trend equipped
