【正文】 s. 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。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 microscopic looks at the transformation the necessity From on microscopic looked below that, the numerical control engine bed has the prominent superiority pared to the traditional engine bed, moreover these superiority e from the puter might which the numerical control system contains. may process the traditional engine bed cannot process the curve, the curved surface and so on the plex ponents. Because the puter 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 plex curve or the curved surface. may realize the processing automation, moreover is the flexible 南 京 理 工 大 學 課程設計說明 書（英文翻譯） 6 automation, thus the efficiency may enhance 3 ~ 7 times pared to the traditional engine bed. Because the puter 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. processings ponents 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 ponents in engine bed between frequent transporting. has autoalarm, the automatic monitoring, automatic pensation 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 worker39。 4 控制 系統(tǒng)的設計，一 A1 圖紙繪制電氣控制原理圖。 5 編寫系統(tǒng)控制軟件，對所附的零件圖編寫數(shù)控加工程序。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, the engine bed numerical control carries out FMC (flexible manufacture unit), FMS (flexible manufacture system) as well as CIMS (puter integration manufacture system) and so on the enterprise being an information based society transformation foundation. The numerical control technology already became the manufacturing industry automation the core technology and the 南 京 理 工 大 學 課程設計說明 書（英文翻譯） 7 foundation technology. great watches the transformation the necessity From on macroscopic looked that, the industry developed country armed forces, the airplane weapon industry, in the end of the 7039。 Moreover, because many years use, the operator already understood to the engine bed characteristic, uses and services the aspect to train the time in the operation short, effective is quick. The transformation engine bed as soon as installs, may realize the capacity load revolution. may fully use the existing condition May fully use the existing ground, does not need to like buys when the new equipment such to have reto construct the ground. may use the newest control technology enhances the production equipment the automated level and the efficiency, improves the equipment quality and the scale, alters to the old engine bed now the horizontal engine bed. Fourth, numerical control system choice When the numerical control system mainly has three kind of types, the transformation, should act according to the special details to carry on 南 京 理 工 大 學 課程設計說明 書（英文翻譯） 11 the choice. Stepbysteps the open system which the electrical machinery drives This system servo drive mainly is stepbysteps the electrical machinery, the power stepbysteps the electrical machinery, the battery solution pulse motor and so on. Entering sends out which by the numerical control system for instruction pulse, after the actuation electric circuit control and the power enlargement, causes to stepbystep the electrical machinery rotation, through gear vice and ball bearing guide screw vice actuation executive ponent. So long as the control mand pulse quantity, the frequency as well as the circular telegram order, then may control the executive ponent movement the displacement quantity, the speed and the heading. This kind of system does not need the physical location and the velocity feedback which obtains to the input end, therefore called it the open system, this system displacement precision mainly decided in stepbysteps the electrical machinery angular displacement precision, transmission part and so on gear guide screw pitches the precision, therefore the system dis
