【正文】 r of the data interchange software of manufacturing industry in the global range, he has already developed the super model (Super Model ) which accuses of information exchange of machine tooling by counting, its goal is to describe all processing courses with the unified norm. Such new data interchange form has already been verified in allocating the SIEMENS, FIDIA and European OSACANC numerical control at present. 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. a. Have established 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 survey basically now, among them most technology have already possessed and mercialized the foundation developed, some technology has already, industrialization mercialized. b. Have 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.. These factories have formed the numerical control industrial base of our country basically. c. Have set up a numerical control research, development, managerial talent39。 Open Manufacturing Environment that the pany exhibits of German Siemens (Siemens ) (open the manufacturing environment, abbreviated as OME),etc., have reflected numerical control machine tooling to the development trend of worked direction. Pay attention to the new technical standard, normal settingup Design the norm of developing about the numerical control system As noted previously, there are better mon ability, flexibility, adaptability, expanding in the open numerical control system, such countries as . ,European Community and Japan ,etc. implement the strategic development plan one after another , carry on the research and formulation of the systematic norm (OMAC , OSACA , OSEC ) of numerical control of the open system structure, 3 biggest economies in the world have carried on the formulation that nearly the same science planned and standardized in a short time, have indicated a new arrival of period of change of numerical control technology. Our country started the research and formulation of standardizing the frame of ONC numerical control system of China too in 2021. About the numerical control standard The numerical control standard is a kind of trend of informationbased development of manufacturing industry. Information exchange among 50 years after numerical control technology was born was all because of ISO6983 standard, namely adopt G, M code describes how processes, its essential characteristic faces the processing course, obviously, he can39。 There are content of intelligence diagnose , intelligent monitoring , diagnosis convenient to be systematic and maintaining ,etc.. Produce the existing problem for the industrialization of solving the traditional numerical control system sealing and numerical control application software. A lot of countries carry on research to the open numerical control system at present, such as NGC of . (The Next Generation WorkStation/Machine Control), OSACA of European Community (Open System Architecture for Control within Automation Systems), OSEC (Open System Environment for Controller) of Japan, ONC (Open Numerical Control System) of China, etc.. The numerical control system melts to bee the future way of the numerical con
