【正文】 Computer Numerical Control Manufacturing第 1單元 計(jì)算機(jī)數(shù)控加工簡(jiǎn)介Reading Target? After reading this unit, you should be able to explain what puter numerical control (CNC) is and what basic ponents prise CNC systems.Text of Computer Numerical Control and its ponents A puter numerical control (CNC) machine is an NC machine with the added feature of an onboard puter. The onboard puter is often referred to as the machine control unit or MCU. CNC的定義及其系統(tǒng)組成 計(jì)算機(jī)數(shù)控機(jī)床就是在 NC機(jī)床的基礎(chǔ)上附加一個(gè)內(nèi)置式計(jì)算機(jī)，這種內(nèi)置式計(jì)算機(jī)通常被稱(chēng)為機(jī)床控制單元或 MCU。簡(jiǎn)單地說(shuō)，數(shù)字控制是基于代碼自動(dòng)操作制造類(lèi)機(jī)床的一種方法，這些代碼由字母、數(shù)字和特殊字符組成。 機(jī)床控制單元：生成、存儲(chǔ)和處理 CNC程序。它們裝有自動(dòng)換刀裝置，可換刀具數(shù)高達(dá) 90把甚至更多。此外，一些加工中心利用分度頭可以對(duì)零件不同的面和特定的角度進(jìn)行加工。Text In addition to machining centers and turning centers, CNC technology has also been applied to many other types of manufacturing equipment. Among these are wire electrical discharge machines (wire EDM) and laser cutting machines. 除加工中心和車(chē)削中心之外， CNC技術(shù)還被廣泛用于其他許多類(lèi)型的設(shè)備，其中包括線切割機(jī)床和激光切割機(jī)。 Text Laser cutting CNC machines utilize an inten
