【正文】 ? Once the program is developed(either manually or with a CAM system), it must be loaded into the CNC control. Though the setup person could type the program right into the control, this would be like using the CNC machine as a very expensive typewriter. If the CNC program is developed with the help of a CAM system, then it is already in the form of a text file . If the program is written manually, it can be typed into any puter using a mon word processor (though most panies use a special CNC text editor for this purpose). Either way, the program is in the form of a text file that can be transferred right into the CNC machine. A distributive numerical control (DNC) system is used for this purpose. A DNC system is nothing more than a puter that is worked with one or more CNC machines. Until only recently, rather crude serial munications protocol (RS232c) had to be used for transferring programs. Newer controls have more current munications capabilities and can be worked in more conventional ways (Ether, etc.). Regardless of methods, the CNC program must of course be loaded into the CNC machine before it can be run. 中文翻譯： 什么 數(shù)控機(jī)床 數(shù)控機(jī)床 代表計(jì)算機(jī)數(shù)字控制 機(jī)床 ， 并且從 20 世紀(jì) 70 年代以來(lái)一直受到人們的關(guān)注。39。39。39。ve used one of the simplest machining operations (drilling) for our example. There are more plicated machining operations that would require a much higher skill level (and increase the potential for mistakes resulting in scrap workpieces) of the person running the conventional machine tool.
