1、附录英文翻译 aaNC Technology 1、 Research current situation of NC lathe in our times Research and development process to such various kinds of new technologies as numerical control lathe , machining center , FMS , CIMS ,etc. of countries all over the world, linked to with the international economic situati

2、on closely. The machine tool industry has international economy to mutually promote and develop, enter 21 alert eras of World Affairs, the function that peoples knowledge plays is more outstanding , and the machine tool industry is regarded as the foundation of the manufacturing industry of the mach

3、ine, its key position and strategic meaning are more obvious. Within 1991-1994 years, the economic recession of the world, expensive FMS, CIMS lowers the temperature, among 1995-2000 years, the international economy increases at a low speed, according to requisition for NC lathe and the world four m

4、ajor international lathes exhibition in order to boost productivity of users of various fields of present world market (EMO , IMTS , JIMTOF , China CIMT of Japan of U.S.A. of Europe), have the analysis of the exhibit, there are the following several points mainly in the technical research of NC lath

5、e in our times: （ 1）、 Pay more attention to new technology and innovation Worldwide , are launching the new craft , new material , new structure , new unit , research and development of the new component in a more cost-effective manner, developmental research of for instance new cutter material , th

6、e new electric main shaft of main shaft structure , high speed , high-speed straight line electrical machinery ,etc. Regard innovating in improvement of the processing technology as the foundation, for process ultra and hard difficult to cut material and special composite and complicated part , irre

7、gular curved surface ,etc. research and develop new lathe variety constantly. （ 2）、 Improve the precision and research of machine tooling In order to improve the machining accuracy of the machining center , are improving rigidity of the lathe , reduction vibration constantly, dispel hotly and out of

8、 shape, reduce the noise , improve the precision of localization of NC lathe , repeat precision , working dependability , stability , precision keeping, world a lot of country carry on lathe hot error , lathe sport and load out of shape software of error compensate technical research, take precision

9、 compensate , software compensate measure improve , some may make this kind of error dispel 60% already. And is developing retrofit constantly, nanometer is being processed. （ 3）、 Improve the research of the machine tooling productivity World NC lathe, machining center and corresponding some develop

10、ment of main shaft , electrical machinery of straight line , measuring system , NC system of high speed, under the prerequisite of boosting productivity. （ 4）、 What a lot of countries have already begun to the numerical control system melt intelligently, openly, study networkedly elligent research o

11、f the numerical control system Mainly showing in the following aspects: It is intelligent in order to pursue the efficiency of processing and process quality, the self-adaptation to the processing course is controlled, the craft parameter produces research automatically； Join the convenient one in o

12、rder to improve the performance of urging and use intelligently, to the feedback control , adaptive operation , discerning automatically load selects models automatically , since carries on research whole definitely ,etc. of the electrical machinery parameter； There are such research of the respect

13、as intelligent automatic programming , intelligent man-machine interface , intelligence diagnosing , intelligent monitoring ,etc. B、 The numerical control system melts and studies open Mainly showing in the following aspects: The development of the numerical control system is on unified operation pl

14、atform, face the lathe producer and support finally, through changing, increasing or cutting out the structure target(numerical control target ), form the seriation, and can use users specially conveniently and the technical know-how is integrated in the control system, realize the open numerical co

15、ntrol system of different variety , different grade fast, form leading brand products with distinct distinction. System structure norm of the open numerical control system at present, norm , disposing the norm , operation platform , numerical control systematic function storehouse and numerical cont

16、rol systematic function software developing instrument ,etc. are the core of present research to pass through. C、 Meeting the manufacture system of the production line , demand for the information integration of the manufacturing company networkedly greatly of numerical control equipment, it is a ba

17、sic unit of realizing the new manufacture mode too. 2、 Classification of the machining center （ 1） Process according to main shaft space position when it classifies to be as follows, horizontal and vertical machining center. Horizontal machining center, refer to the machining center that the axis le

18、vel of the main shaft is set up . Horizontal machining center for 3-5 sport coordinate axis, a common one three rectilinear motion coordinate axis and one turn the coordinate axis of sports round (turn the workingbench round), it can one is it is it finish other 4 Taxi processing besides installing

19、surfaces and top surfaces to insert to install in work piece, most suitable for processing the case body work piece . Compared with strength type machining center it, the structure is complicated, the floor space is large, quality is large, the price is high. Vertical machining center, the axis of t

20、he main shaft of the vertical machining center, in order to set up vertically, its structure is mostly the regular post type, the workingbench is suitable for processing parts for the slippery one of cross, have 3 rectilinear motion coordinate axis generally , can find a room for one horizontal nume

21、rical control revolving stage (the 4th axle ) of axle process the spiral part at workingbench. The vertical machining center is of simple structure, the floor space is small, the price is low, after allocating various kinds of enclosures , can carry on the processing of most work pieces . Large-scal

22、e gantry machining center, the main shafts are mostly set up vertically, is especially used in the large-scale or with complicated form work piece , is it spend the many coordinate gantry machining center to need like aviation , aerospace industry , some processing of part of large-scale steam turbi

23、ne. Five machining centers, this kind of machining center has function of the vertical and horizontal machining center, one is it after inserting , can finish all five Taxi processing besides installing the surface to install in work piece, the processing way can make form of work piece error lowest

24、 , save 2 times install and insert working, thus improve production efficiency , reduce the process cost. (2)Classify by craft use Is it mill machining center to bore, is it mill for vertical door frame machining center , horizontal door frame mill the machining center and Longmen door frame mill th

25、e machining center to divide into. Processing technology its rely mainly on the fact that the door frame is milled, used in case body, shell and various kinds of complicated part special curve and large processes , curved surface of outline process, suitable for many varieties to produce in batches small. Complex machining center, point five times and compound and process mainly,
