Numerical control technology and equipment trend of development The equipment industry technical level and the modernized degree were deciding the entire national economy level and the modernized degree, the numerical control technology and the equipment are the development emerging high technology and new technology industry and the stateofart industry (for example defense industry industries and so on information technology and industry, biological technology and industry, aviation, astronautics) enables the technology and the most basic equipment. Marx had said “each kind of economical time difference, does not lie in produces any, but how lies in produces, with any means of labor production”. The technique of manufacture and the equipment is the humanity produces active the most basic producer goods, but the numerical control technology also is advanced now the technique of manufacture and the equipment most core technology. Now the various countries manufacturing industry widely uses the numerical control technology, sharpens the manufacturing capacity and the level, enhances to the dynamic changeable market adaptiveness and petitive ability. In addition in the world various industries developed country also lists as the national strategic resources the numerical control technology and the numerical control equipment, not only takes the significant measure to develop own numerical control technology and the industry, moreover implements the blockade and the limit policy in “precise and advanced” the numerical control key technologies and the equipment aspect to our country. In brief, develops vigorously take the numerical control technology has bee the world each developed country acceleration economy development as the core advanced technique of manufacture, enhances the prehensive national strength and the national status important way. The numerical control technology is carries on the control with the numerical information to the mechanical movement and the work process the technology, the numerical control equipment is take the numerical control technology as representative39。s new technology the integration of machinery product which forms to the traditional manufacture industry and the emerging manufacturing industry seepage, namely socalled digitized equipment, its technical scope cover very many domains: (1) machine manufacture technology。 (2) information processing, processing, transmission technology。 (3) automatic control technology。 (4) servo actuates the technology。 (5) sensor technology。 (6) software technology and so on. 1 numerical control technology trend of development Not only the numerical control technology application has brought the revolutionary change for the traditional manufacturing industry, causes the manufacturing industry to bee the industrialization the symbol, moreover along with numerical control technology unceasing development and application domain expansion, he to national economy and the people39。s livelihood some important professions (IT, automobile, light industry, medical service and so on) development more and more vital role, because these professions must equip the digitization already was the modern development major tendency. The numerical control technology and the equipment development tendency looked from the present world that, its main research hot spot has following several aspect [1~4]. high speed, high precision work technology and equipment new tendency The efficiency, the quality are the advanced technique of manufacture main bodies. High speed, the high precision work technology may enhance the efficiency enormously, enhances the product the quality and the scale, reduces the production cycle and sharpens the market petition ability. Lists as one of 5 great modern techniques of manufacture for this Japan Tip Technology Resea
