Numerical control technology to go on technology that control with digital information to mechanical movement and working course, numerical control equipment whether represented by technology of numerical control new technology make industry and new developing infiltration electromechanics integrated product that form of manufacturing industry to tradition, . what is called di gitization equip, its technological range covers a lot of fields: (1)Mechanical manufacturing technology。39。 Function part specialized level of production and form a plete set ability to be lower。 Will not have cheap and products rich in the petitiveness without scale 。這些都對加工裝備提出了高速、高精和高柔性的要求。 在可靠性方面，國外數(shù)控裝置的 MTBF 值已達(dá) 6000h 以上，伺服系統(tǒng)的 MTBF 值達(dá)到 30000h 以上，表現(xiàn)出非常高的可靠性。此外世界上各工業(yè)發(fā)達(dá)國家還將數(shù)控技術(shù)及數(shù)控裝備列為國家的戰(zhàn)略物資，不僅采取重大措施來發(fā)展自己的數(shù)控技術(shù)及其產(chǎn)業(yè)，而且在 “ 高精尖 ” 數(shù)控關(guān)鍵技術(shù)和裝備方面對我國實(shí)行封鎖和限制政策。 Numerical control technological application expand efforts to be better。39。39。 in order to improve manufacturing capacity and level, improve the adaptive capacity and petitive power to the changeable market of the trends. In addition every industrially developed country in the world also classifies the technology and numerical control equipment of numerical control as the strategic materials of the country, not merely take the great measure to develop one39。 In order to enhance the actuation performance and the use connection convenient intellectualization, like the feedforward control, the electrical machinery parameter autoadapted operation, the automatic diagnosis load automatic designation model, is automatic entire grades。t meet demands of highspeed development of the technology of modern numerical control 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 offering a kind of neutral mechanism not depending on the concrete system , can describe the unified data model in whole lifespan of the products , thus realize the whole manufacture process, and even the standardization of each industrial field product information. The appear ance of STEPNC may be a revolution of the technical field of the numerical control, on development and even the whole manufacturing industry of the technology of numerical control , 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 single puter. Under the new standard, NC procedure can be dispersed on Inter, this is exactly a direction of open , worked development of technology of numerical control. Secondly, STEPNC numerical control system also can reduce , process (about 75% ) drawing , process procedure work out (about 35% ) time and process (about 50% ) time 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 anizations 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 and accused of the super model (Super Model ) 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, . closed developing stage. In this stages, technology of foreign countries blockade and basic restriction of terms of our country, the development of the technology of numerical control 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 , 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 that on the later stage in the Eighth FiveYear Plan Period of the country and during the Ninth FiveYear Plan Period , 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 the Ninth FiveYear Plan latter stage, domestic numerical control domestic market share of lathe reach 50% , mix domestic numerical control system (popular ) to up to 10%. Review the development course in the past 50 years of technology of numerical control of our country, especially pass the brainstorm of 4 FiveYear Plans, all in all has made following achievements. a. Have establish the foundation of the technical development of numerical control, has basical
