1、Numerical control technology and equiping development trend Equip the engineering level , level of determining the whole national economy of the modernized degree and modernized degree of industry, numerical control technology is it develop new developing new high-tech industry and most advanced ind

2、ustry to equip (such as information technology and his industry, biotechnology and his industry, aviation , spaceflight,etc. national defense industry industry) last technology and getting more basic most equipment. Marx has ever said the differences of different economic times, do not lie in what i

3、s produced , and lie in how to produce, produce with some means of labor . Manufacturing technology and equiping the most basic means of production that are that the mankind produced the activity, and numerical control technology is nowadays advanced manufacturing technology and equips the most cent

4、ral technology. Nowadays the manufacturing industry all around the world adopts numerical control technology extensively, in order to improve manufacturing capacity and level, improve the adaptive capacity and competitive power to the changeable market of the trends . In addition every industrially

5、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 ones own numerical control technology and industry, and implement blockading and restrictive poli

6、cy to our country in view of high-grade , precision and advanced key technology of numerical control and equiping. In a word, develop the advanced manufacturing technology taking numerical control technology as the core and already become every world developed country and accelerate economic develop

7、ment in a more cost-effective manner, important way to improve the overall national strength and national position. Numerical control technology is the technology controlled to mechanical movement and working course with digital information, integrated products of electromechanics that the numerical

8、 control equipment is the new technology represented by numerical control technology forms to the manufacture industry of the tradition and infiltration of the new developing manufacturing industry, namely the so-called digitization is equipped, its technological range covers a lot of fields: (1)Mec

9、hanical manufacturing technology; (2)Information processing , processing , transmission technology; (3)Automatic control technology; (4)Servo drive technology; (5)Technology of the sensor ; (6)Software engineering ,etc. Development trend of a numerical control technology Numerical control technology

10、 in the world at present and equiping the development trend to see, there is the following several respect 1- in its main research focus . 1.A high-speed , high finish machining technology and new trend equipped The efficiency , quality are subjavanufacturing technology. High-speed , high finish mac

11、hining technology can raise the efficiency greatly , improve the quality and grade of the products, shorten production cycle and improve the market competitive power. Japan carries the technological research association first to classify it as one of the 5 great modern manufacturing technologies for

12、 this, learn (CIRP ) to confirm it as the centre in the 21st century and study one of the directions in international production engineering. In the field of car industry, produce one second when beat such as production of 300,000 / vehicle per year, and many variety process it is car that equip key

13、 problem that must be solved one of; In the fields of aviation and aerospace industry, spare parts of its processing are mostly the thin wall and thin muscle, rigidity is very bad, the material is aluminium or aluminium alloy, only in a situation that cut the speed and cut strength very small high,

14、could process these muscles , walls . Adopt large-scale whole aluminium alloy method that blank pay empty make the wing recently, such large-scale parts as the fuselage ,etc. come to substitute a lot of parts to assemble through numerous rivet , screw and other connection way, make the intensity , r

15、igidity and dependability of the component improved. All these, to processing and equiping the demand which has proposed high-speed , high precise and high flexibility. 1.2 Link and process and compound to process the fast development of the lathe in 5 axes Adopt 5 axles to link the processing of th

16、e three-dimensional 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
