【正文】 oval standard, also is the technology preparatory work important link. The debugging work involves the machinery, the hydraulic pressure, the electricity, the control, and so on, therefore must carry on by the project person in charge, other personnel coordinate. The debugging step may conform to simplicity to numerous, from infancy to maturity, carries on from outside to in, after also may the partial overall situation, after first the subsystem the The numerical control transformation superiorly lacks reduced investment costs, the date of delivery are short　　With purchases the new engine bed to pare, may save 60% ~ 80% expense generally, the transformation expense is low. Largescale, the special engine bed especially is specially obvious. The mon largescale engine bed transforms, only spends the new engine bed purchase expense 1/3, the date of delivery is short. But some peculiar circumstances, like the high speed main axle, the tray automatic switching unit manufacture and the installment too requires a lot of work, costs a great deal of money, often transforms the cost to enhance 2 ~ 3 times, with purchases the new engine bed to pare, only can economical invest about 50%. machine capability stable are reliable, the structure is limited Uses foundation and so on lathe bed, column all is heavy but the firm casting ponent, but is not that kind of welding ponent, after the transformation engine bed performance high, the quality is good, may take the new equipment continues to use many years. But receives the original mechanism the limit, not suitably makes the unprecedented transformation. familiar understood the equipment, is advantageous for the operation service When purchases the new equipment, did not understand whether the new equipment can satisfy its processing request. The transformation then otherwise, may precisely calculate the engine bed the processing ability。 When start moment of force and movement the moment of force approaches, may reduce the electrical machinery to start the moment of force. Therefore may satisfiedly pare the high accuracy ponents processing request. safe protection The effect must take the security as a premise. Transforms in the engine bed must take the corresponding measure according to the actual situation, cuts noticeable. The ball bearing guide screw vice is the precision part, when the work must take strict precautions against the dust is specially the scrap and the hard sand grains enters the roller conveyer. On longitudinal guide screw also coca overall sheet iron safety mask. The big carriage with skids two end surfaces which the guide rail contacts to have to seal, prevented absolutely the flinty granulated foreign matter enters the sliding surface damage guide rail.Sixth, After the engine bed electrical system transformation, to operates, the programmers inevitably brings the new request. Therefore ahead of time carries on new system knowledge training to the operator and the programmers to be extremely important, after otherwise will affect the transformation the engine bed rapid investment production. The training content should include the new operation kneading board disposition, the function, the instruction meaning generally。 Manual speed X/Y/The Z axis respectively is 3000/1000/500 mm/Min。 The engine bed smallest migration unit is .3rd, transforms the X53 milling machine with SIEMENS 802S In 2000, the pany invests 120,000 Yuan, with German Simens the 802S numerical control system, stepbysteps the actuation system is the X53 milling machine carries on X, Y, the Z three axle numerical control transformation to pany39?！　?年后，即在1952年，計算機技術(shù)應用到了機床上，在美國誕生了第一臺數(shù)控機床。到1971年，美國INTEL公司在世界上第一次將計算機的兩個最核心的部件運算器和控制器，采用大規(guī)模集成電路技術(shù)集成在一塊芯片上，稱之為微處理器（MICROPROCESSOR），又可稱為中央處理單元（簡稱CPU）。 　　總之，計算機數(shù)控階段也經(jīng)歷了三代。 （1）應用自適應控制技術(shù) 　　數(shù)控系統(tǒng)能檢測過程中一些重要信息，并自動調(diào)整系統(tǒng)的有關(guān)參數(shù)，達到改進系統(tǒng)運行狀態(tài)的目的。 可以實現(xiàn)加工的自動化，而且是柔性自動化，從而效率可比傳統(tǒng)機床提高3～7倍。 　　以上這些優(yōu)越性是前人想象不到的，是一個極為重大的突破。數(shù)控技術(shù)已經(jīng)成為制造業(yè)自動化的核心技術(shù)和基礎技術(shù)。數(shù)控機床只要更換一個程序，就可實現(xiàn)另一工件加工的自動化，從而使單件和小批生產(chǎn)得以自動化，故被稱為實現(xiàn)了柔性自動化。 數(shù)控未來發(fā)展的趨勢 　繼續(xù)向開放式、基于PC的第六代方向發(fā)展 　　基于PC所具有的開放性、低成本、高可靠性、軟硬件資源豐富等特點，更多的數(shù)控系統(tǒng)生產(chǎn)廠家會走上這條道路。這是因為小型計算機功能太強，控制一臺機床能力有富裕（故當時曾用于控制多臺機床，稱之為群控），不如采用微處理器經(jīng)濟合理。近半個世紀以來，數(shù)控系統(tǒng)經(jīng)歷了兩個階段和六代的發(fā)展。 Retained the original main axle system and the cooling system。. The engine bed three coordinates linkage may plete each kind of plex curve or the curved surface processing.2nd, transforms the C6140 lathe with GSK980T and the exchange servo drive system sds In 2000, with Guangzhou numerical control plant production GSK980T numerical control system, the DA98 exchange servo unit and 4 locations automatic tool rests to an electrical machinery branch factory C6140 lathe X, the Z two axes carries on the numerical control transformation。 Maintenance maintenance request。 Native corporation like China Mount Everest Corporation, Beijing astronautics engine bed numerical control system group pany, Central China numerical control pany and Shenyang upscale numerical control country engineering research center. When choice numerical control system mainly is each kind of precision which the engine bed must achieve after the numerical control transformation, actuates the electrical machinery the power and user39。s, at the beginning of the 8039。 1959 second generation of transistor。 Second is NC, the addend reveals the installment on the ordinary engine bed, or adds the numerical control system, transforms the NC engine bed, the CNC engine bed。 The power is big。 Retained the original main axle system and the cooling system。 Maximum speed X/The Z axis respectively is 。 Manual enters for speed X/Y/The Z axis respectively is 。隨著元器件的發(fā)展，這個階段歷經(jīng)了三代，即1952年的第一代電子管；1959年的第二代晶體管；1965年的第三代小規(guī)模集成電路。由于微處理器是通用計算機的核心部件，故仍稱為計算機數(shù)控。遠程通訊，遠程診斷和維修將更加普遍。 2 機床數(shù)控化改造的必要性 微觀看改造的必要性 　　從微觀上看，數(shù)控機床比傳統(tǒng)機床有以下突出的優(yōu)越性，而且這些優(yōu)越性均來自數(shù)控系統(tǒng)所包含的計算機的威力。 擁有自動報警、自動監(jiān)控、自動補償?shù)榷喾N自律功能，因而可實現(xiàn)長時間無人看管加工。除在制造過程中采用數(shù)控機床、FMC、FMS外，還包括在產(chǎn)品開發(fā)中推行CAD、CAE、CAM、虛擬制造以及在生產(chǎn)管理中推行MIS（管理信息系
