ons of a machine in the past two years, if in EMO2020 exhibition, Cyber Production Center that the pany exhibits of mountain rugged campstool gram in Japan (Mazak) (intellectual central production control unit, abbreviated as CPC)。 The lathe pany of Japanese big Wei (Okuma ) exhibits IT plaza (the information technology square , is abbreviated as IT square )。 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 2020. 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。 t meet highspeed development of modern numerical control technology39。 s needs more and more already. For this reason, studying and making a kind of new CNC system standard ISO14649 (STEPNC) in the world, its purpose is to offer a kind of neutral mechanism not depending on the concrete system, can describe the unified data model in cycle of whole life of the products, thus realize the whole manufacture process, standardization of and even each industrial field product information. The appearance of STEPNC may be a revolution of the technological field of the numerical control, on the development and even the whole manufacturing industry of numerical control technology, will exert a farreaching influence. First of all, STEPNC puts forward a kind of brandnew manufacture idea, in the traditional manufacture idea, NC processes the procedures to all concentrate on individual puter. Under the new standard, NC procedure can be dispersed on Inter, this is exactly a direction of open , worked development of numerical control technology. Secondly, STEPNC numerical control system can also reduce and process the drawing (about 75%), process the procedure to work out the time (about 35%) and process the time (about 50%) greatly. At present, AmericanEuropean countries pay much attention to the research of STEPNC, Europe initiates IMS plan () of STEPNC. 20 CAD/CAM/CAPP/CNC users, manufacturers and academic organizations from Europe and Japan participated in this plan. STEP Tools Company of . is a developer 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 contro。
