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 quant
4、itive 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 n
5、early half century, the numerical control system has experienced two stages and six generation of development. 1.1 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 en

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, is called the hardware connection numerical control (HARD-WIRED NC), Jian Chengwei numerical control (NC). Along with t

8、cal 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 fro
9、nt 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 (MICROPROC
10、ESSOR), 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- T
11、aiwan 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-pro
12、cessor 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, 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
