【正文】 Unit 1 Introduction to Computer Numerical Control Manufacturing第 1單元 計算機數(shù)控加工簡介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 計算機數(shù)控機床就是在 NC機床的基礎(chǔ)上附加一個內(nèi)置式計算機，這種內(nèi)置式計算機通常被稱為機床控制單元或 MCU。 NC機床的控制單元通常由硬件構(gòu)成，也就是說機床的功能是由控制器內(nèi)置的物理電子元件控制的。 TextControl units for NC machines are usually hard wired. This means that a machine functions are controlled by the physical electronic elements that are built into the controller. Simply put, numerical control is a method of automatically operating a manufacturing machine based on a code of letters, numbers, and special characters. NC機床的控制單元通常由硬件構(gòu)成，也就是說機床的功能是由控制器內(nèi)置的物理電子元件控制的。簡單地說，數(shù)字控制是基于代碼自動操作制造類機床的一種方法，這些代碼由字母、數(shù)字和特殊字符組成。
