【正文】 the project of key technology is indifferent. The standard of the lathe lags behind, the level is relatively low, it is not enough for new standard of the numerical control system to study. 3 pairs of strategic thinking of technology and industrialized development of numerical control of our country Strategic consideration Our country make big country, industry is it is it accept front instead of transformation of back end to try one39。 It is not enough to analyse to the technological application level and ability of numerical control of our country. （2） System. Pay close attention to numerical control industrialization many in the issue, consider numerical control industrialization little in the issue synthetically in terms of the systematic one, industry chain in terms of technology。s process arduousness , plexity and longterm characteristic of domestic numerical control insufficiently。 It is not strong that the technological application of numerical control expands dynamics。 One39。 Appearance quality is relatively poor。s basic team. Though has made considerable progress in research and development and industrialization of numerical control technology, but we will realize soberly, the research and development of the technology of advanced numerical control of our country, especially there is greater disparity in current situation and current demand of our country of engineering level in industrialization. Though very fast from watching the development of our country vertically, have disparity horizontally more than (pare foreign countries with) not merely engineering level, there is disparity too in development speed in some aspects, namely the engineering level disparity between some highgrade , precision and advanced numerical control equipment has the tendency to expand . Watch from world, estimate roughly as follows about the engineering level of numerical control of our country and industrialization level. （1） On the engineering level, in probably backward 101 years with the advanced level in foreign countries, it is bigger in highquality precision and sophisticated technology. （2） On the industrialization level, the occupation rate of market is low, the variety coverage rate is little, have not formed the largescale production yet。t meet highspeed development of modern numerical control technology39。 The lathe pany of Japanese big Wei (Okuma ) exhibits IT plaza (the information technology square , is abbreviated as IT square )。 The ones that simplified programming , simplified operating aspect are intelligent, for instance intelligent automatic programming , intelligent manmachine interface ,etc.。 The speed and acceleration of main shaft of dual main shaft lathes of Germany DMG Company are up to 120000r/mm and 1g. In machining accuracy, the past 10 years, ordinary progression accuse of machining accuracy of lathe bring 5μm up to from 10μm already, accurate grades of machining center from 3～5μm, rise to 1～, and ultraprecision machining accuracy is it enter nanometer grade to begin already (). In dependability, MTBF value of the foreign numerical control device has already reached above 6 000h, MTBF value of the servo system reaches above 30000h, demonstrate very high dependability . In order to realize highspeed, high finish machining, if the part of function related to it is electric main shaft, straight line electrical machinery get fast development, the application is expanded further . Link and process and pound to process the fast development of the lathe in 5 axes Adopt 5 axles to link the processing of the threedimensional curved surface part, can cut with the best geometry form of the cutter , not only highly polished, but also efficiency improves by a large margin . It is generally acknowledged, the efficiency of an 5 axle gear beds can equal 2 3 axle gear beds, is it wait for to use the cubic nitrogen boron the milling cutter of ultra hard material is milled and pared at a high speed while quenching the hard steel part, 5 axles link and process 3 constant axles to link and process and give play to higher benefit. Because such reasons as plicated that 5 axles link the numerical control system , host puter structure that but go over, it is several times higher that its price links the numerical control lathe than 3 axles , in addition the technological degree of difficulty of programming is relatively great, have restricted the development of 5 axle gear beds. At present because of electric appearance of main shaft, is it realize 5 axle plex main shaft hair structure processed to link greatly simplify to make, it makes degree of difficulty and reducing by a large margin of the cost, the price disparity of the numerical control system shrinks. So promoted 5 axle gear beds of head of plex main shaft and pound to process the development of the lathe (process the lathe including 5). At EMO2001 exhibition, new Japanese 5 of worker machine process lathe adopt plex main shaft hair, can realize the processing of 4 vertical planes and processing of the wanton angle, make 5 times process and 5 axles are processed and can be realized on the same lathe, can also realize the inclined plane and pour the processing of the hole of awls. Germany DMG Company exhibits the DMUVoution series machining center, but put and insert and put processing and 5 axles 5 times to link and process in once, can be controlled by CNC system or CAD/CAM is controlled directly or indirectly. Bee the main trend of systematic development of contemporary numerical control intelligently, openly, networkedly.The numerical control equipment in the 21st century will be sure the intelligent system, the intelligent content includes all respects in the numerical control system: It is intelligent in order to pursue the efficiency of processing and process quality, control such as the selfadaptation of the processing course, the craft parameter is produced aut
