hange to 1, such as the figure 6 bs show, in the meantime, from adjust to carry on the back to press the valve valve Xin bottom to carry diameter is increase by the original 10 mms for the 13 mms, damping triangle slot side long let up a mms from the original lmm, canmake slippery pedestal of ex hurtle quantity to let up 30%, transfer the process obviouslyshortens for time and slip the exercise of pedestal steady to get to very greatly improve. Six, conclusion Imitate a true research through theories analysis and calculator, from adjust to carry on the back to press to adjust soon system Be bine a drive of the tool machine slippery pedestal system to have much of expansion use main factor which influences a slippery pedestal dynamic state characteristic is oil urn internal structure with from adjust to carry on the back topress valve of as to it39。 s carry on a reasonable design, the dynamic state characteristic canmake to slip a pedestal is shown Zhao ground an explained adoption power in make to slip a pedestal is shown Zhao ground an explained adoption power inplications not line is convenience valid of. In 1946 the first electronic accounting machine was born in the world, thisindicated the humanity created has been possible to strengthen and partially toreplace 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, thetraditional enginebed hashad the archery target change. Since nearly half century, the numerical control system has experienced two stages and six generation of development. 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 (HARDWIREDNC), Jian Chengwei numerical control (NC). 6 Along with the primary devicedevelopment, this stage has had been through repeatedly three generations, namely 1952first generation of electron tube。 1959second generation of transistor。 1965 third generation small scale integration electric circuit. In 1970, the general miniputer already appeared and the mass production. Thereupon transplants it takes the numerical control system the core part, from this time on entered the puter numerical control (CNC)the stage (which shouldhave puter in front of the general two characters to abbreviate). In 1971, American INTEL Corporation in the world first time the puter two most cores part logic units and the controller, used the large scale integrated circuit technology integration on together the chip, called it the microprocessor (MICROPROCESSOR),alsomightbe called the centralprocessing element (tobe calledCPU). The microprocessor is applied to 1974 in the numerical control system. This is because miniputer function too strong, controlled an engine bed ability to have wealthily (therefore once uses in controlling the multi Taiwan engine bed at that time, called it group control), was inferior to used the microprocessor economy to be reasonable. Moreover then small machine reliability was not ideal. The early microprocessor speed and the function although insufficiently are alsohigh, but may solve through the multiprocessor structure. Because the microprocessor is the generalpurpose calculator core part, therefore still was called the puter numerical control. In 1990, PC machine (personal puter, domestic custom had called microputer) the performance has developed to the very high stage, may satisfiedly take the numerical control system core part the request. The numerical control system henceforth entered based on the PC stage. In brief, the puter numerical control stage has also experienced three generations. Namely 1970fourth generation of miniputer。 1974five dynasties microprocessor and 1990sixth generation (overseaswascalledPCBASED) based on PC. onto this path. Uses PC machine to take at least its front end machine, processes the manmachine contact surface, the programming, the and so on correspondence, undertakes the numerical control duty by the original system. PC machine has the friendly manmachine contact surface, will popularize to all numerical controls system. The longdistancemunication, the longdistance diagnosis and the service will be more mon. Along with the artificial intelligence in the puter domain unceasing seepage and the development, the numerical control system intellectualized degree unceasingly will enhance. applies the adaptive control technology 7 The numerical controlsystem can examine in theprocess some important information, and the automatic control system related parameter, achieves the improvement system running status the goal. introduces the expert system instruction processing The skilled worker and expert39。 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. introduces the breakdown to diagnose the expert system 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 From on microscopic looked below tha。
