The software and hardware resources has which based on PC are rich and so on the characteristic, the more numerical controls serial production factory can step onto this path. Uses PC machine to take at least its front end machine, processes the man-machine contact surface, the programming, the association
Question and so on net correspondence, undertakes the numerical control duty by the original system. PC machine has the friendly man-machine contact surface, will popularize to all numerical controls system. The long-distance communication, the long-distance diagnosis and the service will be more common.
1.3.2 approaches and the high accuracy development
This is adapts the engine bed to be high speed and the high accuracy direction need to develop.
1.3.3 develops to the intellectualized direction
Along with the artificial intelligence in the computer domain unceasing seepage and the development, the numerical control system intellectualized degree unceasingly will enhance.
(1) applies the adaptive control technology
The numerical control system can examine in the process some important information, and the automatic control system related parameter, achieves the improvement system running status the goal.
(2) introduces the expert system instruction processing
The skilled worker and expert'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
2.1 microscopic looks at the transformation the necessity
From on microscopic looked below that, 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.
2.1.1 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 the synthesis complex curve or the curved surface.
2.1.2 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 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".
2.1.3 processings components precision high, size dispersion degree small, makes the assembly to be easy, no longer needs "to make repairs".
2.1.4 may realize the multi- working procedures centralism, reduces the components in engine bed between frequent transporting.
2.1.5 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.
2.1.6 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. 数控机床改造英文文献和中文翻译(2):http://www.751com.cn/fanyi/lunwen_54038.html
