, simplified operating aspect are intelligent, for instance intelligent automatic programming , intelligent manmachine interface ,etc.。 There are content of intelligence diagnose , intelligent monitoring , diagnosis convenient to be systematic and maintaining ,etc.. 2 pairs of basic estimations of technology and industry development of numerical control of our country The technology of numerical control of our country started in 1958, the development course in the past 50 years can roughly be divided into 3 stages: The first stage is from 1958 to 1979, namely closed developing stage. In this stages, because technology of foreign countries blockade and basic restriction of terms of our country, the development of numerical control technology is paratively slow. During Sixth FiveYear Plan Period , the Seventh FiveYear Plan Period of the country in second stage and earlier stage in the Eighth FiveYear Plan Period , namely introduce technology, digest and assimilate, the stage of establishing the system of production domesticization arisesing tentatively. At this stage , because of reform and openingup and national attention , and study the improvement of the development environment and international environment, research , development and all making considerable progress in production domesticization of the products of the technology of numerical control of our country. The third stage is and during the Ninth FiveYear Plan Period on the later stage in the Eighth FiveYear Plan Period of the country, namely implement the research of industrialization, enter market petition stage. At this stage , made substantive progress in industrialization of the domestic numerical control equipment of our country. In latter stage for the Ninth FiveYear Plan , the domestic occupation rate of market of the domestic numerical control lathe is up to 50%, it is up to 10% too to mix the domestic numerical control system (popular ). Make a general survey of the development course in the past 50 years of technology of numerical control of our country, especially through tackling key problems of 4 FiveYear Plans, all in all has made following achievements. establish the foundation of the technical development of numerical control, has mastered modern numerical control technology basically. Our country has already, the numerical control host puter , basic technology of special plane and fittings grasped and driven from the numerical control system and servoly basically now, among them most technology have already possessed and mercialized the foundation developed , some technology has already, industrialization mercialized. formed the industrial base of numerical control tentatively. In tackling key problems the foundation that the achievement and some technology mercialize , set up the systematic factories of numerical control with production capacity in batches such as numerical control in Central China , numerical control of the spaceflight etc.. Electrical machinery plant of Lanzhou, such factory and the first machine tool plant of Beijing , the first machine tool plant of Jinan ,etc. several numerical control host puter factories of a batch of servo systems and servo electrical machineries as the numerical control in Central China,etc..。
