【正文】 The kit system, perfect training, the service network...etc. that have no high quantity of establishment integrity prop up the system. bad mechanism result in loss of talented people, again check and supervision technique and the technique route innovation, product creative, and check and supervision programming of valid implement, usually program ideal, implement difficulty. business enterprise is in the technique aspect the independent creative ability is not strong, the technical engineering of core turns the ability not tool 。To the market not norm, the blockader of the abroad adds to strangle, system etc. the difficulty estimate shortage。The number controls the technique application realm to expand the strength not strong。t176。The credibility is not high, mercializing the degree shortage。The function parts profession turns to produce the level and bee an ability lower。( the information technique square, the brief name IT square)The Open Manufacturing Environment( open to make the environment, the brief name OME) of German Siemens( Siemens) pany exhibition etc., reflected the number to control the trend that the tool machine processes toward network to turn the direction development. Value the establishment of the new technique standard, norm As for number control the system design development norm Such as front say, the open type number control the system contain better and in general use, gentle, adaptability, expand sex, total body in the United States, Europe similar to Japanese etc. country carry out the strategic development plan in succession, and carry on the research and establishments that the open type system structure number controls the system norm( OMAC, OSACA, OSEC), biggest economy of world carried on in the short date almost science plan and establishment of norms, indicated that the number controls a new approach of period change of our country also starts carry on the research and the establishment of the norm frame that the ONC of China number controls the system in 2000. As for number control the standard The number controls the standard is a kind of trend of the informationbased development of manufacturing number controls 50 years that the technique naissance is behinds, information mutations of are all according to the ISO6983 standard, then the adoption G, the M code description how( how) process, its essence characteristic is to face to process the process, obviously, he has already canned satisfy the demand that the modern number controls the highspeed development of technique less and this, international top just study and draw up a kind of ISO14649( the STEP － NC) with standard new system of CNC, its purpose is provide a kind of not is depend on in the concrete system of neutral mechanism, can describe the whole life cycle of product inside of unify the data model, thus carry out the whole manufacturing process, is to go to the each industry realm product information to standardize. The emergence of the STEP NC may be a number to control a revolution of the technique realm, controling for the number the technical development is to go to the whole manufacturing industry, will produce the profound , the STEP NC puts forward one manufacturing that kind is brandnew principle, in the traditional manufacturing principle, the NC processes the procedures all concentrated pute in the single on under the new standard, the procedure of NC can scatter on the Internet, this counts to control the direction that the technique open type, network turns the development next in order, the STEP NC number control the system and can also reduce to process the diagram paper( about 75%) and process the procedure establishment time( about 35%) and process time consumedly.( about 50%) Currently, the Europe and America nation values the research of the STEP NC verymuch,EuropestartedtheIMS plan of the STEP NC.()Attend this plannedly es from Europe and 20 CAD/ CAM/ CAPP/ CNC customer, factories and academic organization of pany of STEP Tools of the United States is the developer that the manufacturing industry data inside the global scope exchanges the software, he hases already developped to used to the super model( the Super Model) that the number controls the tool machine to process the information mutation, its target is to use the united norm description all process the this kind of new data exchange format already at provide with the SIEMENS, FIDIA and the OSACA NC in Europe numbers to control the system of prototype kind is on board to carry on the verification. 2 Control basic estimate of of technique and its industry development to the our country number The our country number controls the technique start in 1958, being close to 50 years of development process can is divided into 3 stages mostly:The first stage is from the from 1958 to 1979, then close the type development this stage, from the conditional restrict of the technique blockader of the outside the country and the foundation of the our countries, the number controls the technical development to pare for the slowness.65 and75 periodses that second stage is at nation and85 of front expect, then usher in the technique, digesting the absorption, the initial establishment rise the national product turns the system this stage, open because of the reform and the value of the nation, and research development environment and international environment of improvement, our country number control the technical research, development and turned the aspect to all obtain the substantial progress in the national product of the third stage expects after nation of85 of and95 periods, then the implement research that industry turn, enter the market petition this stage, our country domestic the number controled the industry of the material to turn to obtain the materiality 95 last phaseses, the domestic nu
