【正文】 1 外文翻譯 ○ 1 The numerical control technology Numerical control technology is refers with digital, the writing and the mark position digital mand realizes one or the multiTaiwan mechanical device movement control controls usually is the position, the angle, the speed and so on the mechanical quantity and flows to the related switch quantity with the mechanical numerical control production relies on data carrier and the binary mode data operation 1908, perforation sheet metal exchange type data carrier being published。 19 century39。s ends, and have the assistance 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 puter, including puter numerical control system numerical control technology is develops with the engine bed control close 1952, first numerical control engine bed being published, became in the world mechanical industry history an epochmaking event, impelled the automated development. Because uses the puter substitution originally to use the numerical control installment which the hardware logic circuit poses, causes the datain the storage, processing, the operation, the logical judgment and so on each kind of control function realization, may plete through the puter software. The numerical control engine bed is one kind of technical denseness and the automaticity very high integration of machinery processing equipment, is synthesizes the application puter, the automatic control, the automatic detection and precise…The processing precision is high, the quality easy to guarantee, t he prospects for development are extremely broad, therefore the grasping numerical control lathe processing programming technology especially is important. Now, the numerical control technology also is called the puter numerical control technology, at present it is uses the puter realization digital process control the kind of technology according to the control procedure which stores beforehand carries out with the puter to the equipment the control function. ○ 2 Machine tool numerical control system 2 1 .Applies PC resource broadly The microputer the personal puter (PC) is called in recent years develops very quickly , the largescale integrated circuit makes the technology high speed sending out speed , feasible PC hardware structure poses very small. Host CPU operation speed is more and more high. The IPC386 basic frequency is 33 MHz , IPC486 , 58639。s basic frequency may amount 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 e down , reliability improves. That in development of software aspect, OS, the Windows application, feasible PC operation are simpler and convenient especially is perating. 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 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 largescale integrated 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 threedimensional body assembling , have equipped entire CNC with the request posing very small, to adapt to machinery manufacturing industry integration of machinery with electronics. 3..Improves manmachine 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 equipment childbirth factory effort field improves manmachine 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 pany gives birth to a child FAGOR 8050 series , the editors who adopt the each other 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 operation 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 semiautomatic or fullautomatic treating. The various automation operation is not all elected if the face ply is upper, location value and chief axis rotation rate being CNC system39。s 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 .Raises numerical control system product plete 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 ponent. A numerical control system 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
