【正文】 the numerical control technological transformations engine bed and the production line, has formed the engine bed and the production line numerical control transformation new profession. In US, the engine bed transformation industry is called the engine bed regeneration (Remanufacturing) industry. Is engaged in the regeneration industry famous pany to include: The Bertsche engineering firm, the ayton engine bed pany, 外文資料翻譯 第 6 頁(yè) DevliegBullavd (are valuable) serves the group, the US equipment pany and so on. The American valuable pany has set up the pany in China. In Japan, the engine bed transformation industry is called the engine bed to reequip (Retrofitting) industry. Is engaged in the reequipment industry famous pany to include: Big indentation project group, hillock three mechanical panies, thousand substitute fields labor machine pany, wild engineering firm, shore field engineering firm, mountain this engineering firm and so on. Numerical control transformation content The engine bed and the production line numerical control transformation main content has following several points: First is extensively recovers the function, to the engine bed, the production line has the breakdown partially to carry on the diagnosis and the restoration。s experience, the processing general rule and the special rule store in the system, take the craft parameter database as the strut, the establishment has the artificial intelligence the expert system. (3) introduces the breakdown to diagnose the expert system (4) intellectualized numeral servo drive May through the automatic diagnosis load, but the automatic control parameter, causes the actuation system to obtain the best movement. Second, engine bed numerical control transformation necessity microscopic looks at the transformation the necessity From on microscopic looked below that, the numerical control engine bed has the prominent superiority pared to the traditional engine bed, moreover these superiority e from the puter might which the numerical control system contains. may process the traditional engine bed cannot process the curve, the curved surface and so on the plex ponents. Because the puter has the excellent operation ability, may the instant accurately calculate 外文資料翻譯 第 4 頁(yè) each coordinate axis instant to be supposed the movement physiological load of exercise, therefore may turn round the synthesis plex curve or the curved surface. may realize the processing automation, moreover is the flexible automation, thus the efficiency may enhance 3 ~ 7 times pared to the traditional engine bed. Because the puter has the memory and the memory property, may the procedure which inputs remember and save, then the order which stipulated according to the procedure automatic carries out, thus realization automation. The numerical control engine bed so long as replaces a procedure, may realize another work piece processing automation, thus causes the single unit and the small batch of production can automate, therefore is called has realized flexible automation. processings ponents precision high, size dispersion degree small, makes the assembly to be easy, no longer needs to make repairs. may realize the multi working procedures centralism, reduces the ponents in engine bed between frequent transporting. has autoalarm, the automatic monitoring, automatic pensation and so on the many kinds of autonomy function, thus may realize long time nobody to safeguard the processing. advantage which derives by above five. For example: Reduced worker39。外文資料翻譯 第 1 頁(yè) 畢業(yè)設(shè)計(jì)數(shù)控機(jī)床外文翻譯 The Numerical Control Engine Bed Transforms Harvey ackey First numerical control system development summary brief history and tendency In 1946 the first electronic accounting machine was born in the world, this indicated the humanity created has been possible to strengthen and partially to replace the mental labor the tool. It with the humanity these which in the agriculture, the industry society created only is strengthens the physical labor the tool to pare, got up the quantitive leap, entered the information society for the humanity to lay the foundation. After 6 years, in 1952, puter technology applied to the engine bed , the first numerical control engine bed were born in US. From this time on, the traditional engine bed has had the archery target change. Since nearly half century, the numerical control system has experienced two stages and six generation of development. Numerical control (NC) stage (1952 ~ 1970) The early puter operating speed is low, was not big to then science putation and the data processing influence, but could not adapt the engine bed realtime control request. The people can not but use numeral logic circuit to build to bee an engine bed special purpose puter to take the numerical control system, is called the hardware connection numerical control (HARDWIRED NC), Jian Chengwei numerical control (NC). Along with the primary device development, this stage has had been through repeatedly three generations, namely 1952 first generation of electron tube。 1974 five dynasties microprocessor and 1990 sixth generation (overseas was called PCBASED) based on PC. Also must point out, although overseas already renamed as the puter numerical control (namely CNC). Also must point out, although overseas already renamed as the puter numerical control (namely CNC), but our country still the custom called the numerical control (NC). Therefore we daily say numerical control, the materially already was refers to puter numerical control. the numerical control future will develop tendency open style continues to, to develop based on the PC sixth generation of direction The software and hardware resources has which based on PC are rich and so on th
