1、 1 外文翻译 1 The numerical control technology Numerical control technology is refers with digital, the writing and the mark composition digital command realizes one or the multi-Taiwan mechanical device movement control technology.It controls usually is the position, the angle, the speed and so on the

2、mechanical quantity and flows to the related switch quantity with the mechanical energy.The numerical control production relies on data carrier and the binary mode data operation appearance.In 1908, perforation sheet metal exchange type data carrier being published； 19 centurys ends, and have the as

3、sistance function control system take the paper as the data carrier to invent； In 1938, Shannon has carried on the data fast operation and the transmission in the American Massachusetts Institute of Technology, has established the modern computer, including computer numerical control system foundati

4、on.The numerical control technology is develops with the engine bed control close union.In 1952, first numerical control engine bed being published, became in the world mechanical industry history an epoch-making event, impelled the automated development. Because uses the computer substitution origi

5、nally to use the numerical control installment which the hardware logic circuit composes, causes the data-in the storage, processing, the operation, the logical judgment and so on each kind of control function realization, may complete through the computer software. The numerical control engine bed

6、is one kind of technical denseness and the automaticity very high integration of machinery processing equipment, is synthesizes the application computer, the automatic control, the automatic detection and preciseThe processing precision is high, the quality easy to guarantee, t he prospects for deve

7、lopment are extremely broad, therefore the grasping numerical control lathe processing programming technology especially is important. Now, the numerical control technology also is called the computer numerical control technology, at present it is uses the computer realization digital process contro

8、l the technology.This kind of technology according to the control procedure which stores beforehand carries out with the computer to the equipment the control function. 2 Machine tool numerical control system 2 1 .Applies PC resource broadly The microcomputer the personal computer (PC) is called in

9、recent years develops very quickly , the large-scale integrated circuit makes the technology high speed sending out speed , feasible PC hardware structure composes very small. Host CPU operation speed is more and more high. The IPC386 basic frequency is 33 MHz , IPC486 , 586s basic frequency may amo

10、unt to 50 120 MHz, recently Intel gallop the processor (Pentium) , basic frequency already amount to 450 MHz. Memory capacities are also very big , volume is very small, since being that mass production , messenger cost come down , reliability improves. That in development of software aspect, OS, th

11、e Windows application, feasible PC operation are simpler and convenient especially is penetrating. From minitype, machine , the workstation build the CAD/CAM software in large amount to PC transplanting , Sanweitu display and handicraft data base on PC. The opening to the outside world plus PC , the

12、 technician who attracts a great quantity have thrown into the software exploitation , feasible PC software resource has enriched extremely. 2. Miniaturizes to satisfy the integration of machinery with electronics request With the development of microelectronics technology, the large-scale integrate

13、d circuit integration level is more and more high , volume is more and more small. The numerical control equipment factory adopt grand scale IC and adopt the surface installation handicraft (SMT), have realized three-dimensional body assembling , have equipped entire CNC with the request composing v

14、ery small, to adapt to machinery manufacturing industry integration of machinery with electronics. 3.Improves man-machine interface , convenience of customers is put into use For making operation person can handle very easy to have numerical control machine tool in hand, the numerical control equipm

15、ent childbirth factory effort field improves man-machine interface , facilitates a programming , adopt an interactive mode to the full , makes a consumer be put into use going to the lavatory, if the Spain FAGOR company gives birth to a child FAGOR 8050 series , the editors who adopt the each other

16、dyadic editor program to guide system , simplification procedure, use the brief table editor program , make use of a blueprint to build procedure. Whose 8050 TC type numerical control system, has been called (FAGOR800 series CNC system) dyadic top grade fool numerical control system , whose operatio

17、n face ply has been used the sign key , the consumer can according to what be needed the queen who processes a part , chooses a job gram , imports the artwork data, be OK to realize 3 semi-automatic or full-automatic treating. The various automation operation is not all elected if the face ply is up

18、per, location value and chief axis rotation rate being CNC systems turn to demonstrate a coordinate axis only, each axes handling person being able to use the sway a handle or electronic hand wheel to the machine tool carry out manual operation , are put into use going to the lavatory extremely. 4 .

19、Raises numerical control system product complete set Numerical control system includes the CNC device , the chief axis and feeds the servo driving device, and as well as the chief axis electric motor, feeds an electric motor than pertinent detecting couples back a component. A numerical control syst

20、em function goodness and badness is that the function is closely related to as said or narrated above each links. For the need satisfying the machine tool consumer factory, the numerical control equipment childbirth factory takes numerical control product complete set seriously all very much , makes

21、 each systematic links can mate very good , makes a consumer gain best effect. 5. Research and development intelligence type numerical control system So-called intelligence type numerical control system , morning are in the eighties initial stage already begin to study. FS15 series that the FANUC co

22、mpany debuted at that time, will be called AI (artificial intelligence) CNC system , be been to have adopt the expert system in the field of malfunction diagnose mainly. System makes use of so-called reasoning software , analyses and seeks malfunction cause according to the experience storing in kno

23、wledge base in system. The nearest FANUC company goes to in the childbirth system being carried out quilt being called problem IMS (Intelligent Manufacturing Systems) being oriented toward the 21st century , will be technology of world range experienced worker key (Know how) combination be carried o

24、ut seamlessly (Seamless). Subsequently industrial technology desire for development, fabrication process quicker, easier, use fit in with give birth to a child need, one kind be called intelligence closed cycle treating (Intelligent Closed-Loop Processes ICLP) technology adopt. This technology is to

25、 make use of a sensor to gain timely information, to strengthen a maker getting the best product ability. Pursue 1 it is intelligence closed cycle to process a model. 6 .Needs the numerical control product good for sale , develops according to the marketplace The high and new technology is a direction that numerical control system
