Engine bed numerical control transformation necessity

Engine bed numerical control transformation necessity 
 microscopic looks at the transformation the necessity    
From on microscopic looked below that, Cnc machining the numerical control engine bed has the prominent superiority compared to the traditional engine bed, moreover these superiority come from the computer might which the numerical control system contains
 May process the traditional engine bed cannot process the curve, the curved surface and so on the complex components.
  Because the computer has the excellent operation ability, may the instant accurately calculate each coordinate axis instant to be supposed the movement physiological load of exercise, therefore may turn round thesynthesis complex curve or the curved surface.
  may realize the processing automation, moreover is the flexible automation, thus the efficiency may enhance 3 ~ 7 times compared to the traditional engine bed
 Because the computer has the memory and the memory property, may the procedure which inputs remember and save, then Cnc machining 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 components 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 components in engine bed between frequent transporting.  
  Has auto-alarm, the automatic monitoring, automatic compensation 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 worker's labor intensity, saved the labor force (a person to be possible to safeguard the multi- Taiwan engine bed), reduced the work clothes, reduced the new product trial manufacturing cycle and the production cycle, might to the market demand make rapid reaction and so on. 

  Above these superiority are the predecessor cannot imagine, is an extremely significant breakthrough. In addition, Cnc machining the engine bed numerical control carries out FMC (flexible manufacture unit), FMS (flexible manufacture system) as well as CIMS (computer integration manufacture system) and so on the enterprise becoming an information based society  transformation foundation. The numerical control technology already became the manufacturing industry automation the core technology and the foundation technology

The Numerical Control Engine Bed Transforms

The Numerical Control Engine Bed Transforms
 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. Cnc machining It with the humanity these which in the agriculture, the industry society created only is strengthens the physical labor the tool to compare, got up the quantitive leap, entered the information society for the humanity to lay the foundation. 
  After 6 years, in 1952, computer 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 computer operating speed is low, was not big to then science computation and the data processing influence, but could not adapt the engine bed real-time control request. The people can not but use numeral logic circuit "to build" to become an engine bed special purpose computer to take the numerical control system, Cnc machiningis called the hardware connection numerical control (HARD-WIRED 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; 1959 second generation of -- transistor; 1965 third generation -- small scale integration electric circuit.
 Computer numerical control (CNC) stage (in 1970 ~ present) 
 In 1970, the general minicomputer already appeared and the mass production. Thereupon transplants it takes the numerical control system the core part, from this time on entered the computer numerical control (CNC) the stage ("which should have computer in front of the general" two characters to abbreviate). In 1971, American INTEL Corporation in the world first time the computer 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), also might be called the central processing element (to be called CPU)
 The microprocessor is applied to 1974 in the numerical control system. This is because minicomputer 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 also high, but may solve through the multi-processor structure. Because the microprocessor is the general-purpose calculator core part, therefore still was called the computer numerical control
 In 1990, PC machine (personal computer, domestic custom had called microcomputer) the performance has developed to the very high stage,Cnc machining 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 computer numerical control stage has also experienced three generations. Namely 1970 fourth generation of -- minicomputer; 1974 five dynasties -- microprocessor and 1990 sixth generation -- (overseas was called PC-BASED) based on PC.
   Also must point out, although overseas already renamed as the computer numerical control (namely CNC).  

  Also must point out, although overseas already renamed as the computer 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 "computer numerical control".
