1、The development of the numerical control technologyNumerical control technology is the technology controlled to mechanical movement and working course with digital information, integrated products of electromechanics tha

2、t the numerical 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,

3、 namely the so-called digitization is equipped, its technological range covers a lot of fields: (1)Mechanical manufacturing technology; (2)Information processing, processing, transmission technology; (3)Automatic contr

4、ol technology; (4)Servo drive technology; (5)Technology of the sensor; (6)Software engineering ,etc. 1、Development Development trend trend of of a numerical numerical control control technology technologyThe application

5、of numerical control technology has not only brought the revolutionary change to manufacturing industry of the tradition, make the manufacturing industry become the industrialized symbol , and with the constant

6、development of numerical control technology and enlargement of the application, the development of some important trades (IT , automobile , light industry , medical treatment ,etc. ) to the national economy and

7、 the people's livelihood of his plays a more and more important role, because the digitization that these trades needed to equip has already been the main trend of modern development.Numerical control technology in

8、the world at present and equipping the development trend to see, there is the following several respect [1- 4] in its main research focus. 1.2 1.2、A high-speed, high-speed, high high finish finish machining ma

9、chining technology technology and and new new trend trend equipped equippedThe efficiency, quality are subjavanufacturing technology. High-speed, already reached 60 000r/min. Processing a thin wall of pla

10、ne parts, spend 30min only, and same part general at a high speed milling machine process and take 3h, the ordinary milling machine is being processed to need 8h; The speed and acceleration of main shaft of

11、 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,

12、 accurate grades of machining center from 3～5μm, rise to 1～1.5μm, and ultraprecision machining accuracy is it enter nanometer grade to begin already (0.01μm). In dependability, MTBF value of the foreign numerical control

13、 device has already reached above 6 000h, MTBF value of the servo system reaches above 30000h, demonstrate very high dependability . In order to realize high-speed, high finish machining, if the part of function relate

14、d to it is electric main shaft, straight line electrical machinery get fast development, the application is expanded further . 1.2 Link and process and compound to process the fast development

15、 of the lathe in 5 axes Adopt 5 axles to link the processing of the three-dimensional curved surface part, can cut with the best geometry form of the cutter , not only highly polished, but also efficienc

16、y improves by a large margin . It is generally acknowledged, the efficiency of an 5 axle gear beds can equal 3 axle gear beds, is it wait for to use the cubic nitrogen boron the milling cutter of ultra har

17、d 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 compl
