The technique of manufacture and the equipment is the humanity produces active the most basic producer goods, but the numerical control technolog
4、y 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 com
5、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, mo

In brief, develops vigorously take the numerical control technology has become the world each developed country acceleration economy developme

9、 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 developmentNot on
10、ly the numerical control technology application has brought the revolutionary change for the traditional manufacturing industry, causes the manufacturing industry to become the industrialization the symbol, moreover along with numerical control technology unceasing development and application domain
11、 expansion, he to national economy and the peoples 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 nume

13、re 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 competition ability. Lists as one of 5 great modern techniques of manufacture for this Japan Tip
14、Technology Research board it, the international production project learns (CIRP) its determination is one of 21st century central research directions.In the passenger vehicle industry domain, yearly produces 300,000 production metres was 40/s，moreover the multi-variety processing is one of key quest
15、ions which the passenger vehicle equipment must solve; In the aviation and the astronavigation industry domain, its processing spare part many for the thin wall and the thin muscle, the rigidity is very bad, material for aluminum or aluminum alloy, only then in the high cutting speed and the cutting
16、 force very small situation, can to these muscles, the wall carry on the processing. Recently uses the large-scale overall aluminum alloy semifinished materials “pull out spatially” the method to make the wing, the fuselage and so on the large-scale components substitutes many components through the multitudinous rivets, the bolt and other joint way assembling, causes the component the intensity, the rigidity and the reliability obtains the enhancement. These all
