【正文】 A plete set of coded instructions for executing an operation is called a program. Such programs are stored in RAM or the randomaccess memory portion of the puter. They can be played back, edited, and processed by the control. Thus, the machine functions are encoded into the puter at the time of manufacture. 所謂的程序就是用于執(zhí)行某一操作的一整套代碼表示的指令，而這些程序是存放在計算機的隨機存儲器中的，控制器可以對它們進(jìn)行重新調(diào)用，編寫以及處理等操作。因此，我們可以通過對計算機進(jìn)行編碼從而在加工時實現(xiàn)機床操作的各種功能。Text The ponents found in many CNC systems are shown in Figure 11 . Machine control unit: generates, stores and processes CNC programs. The machine control unit also contains the machine motion controller in the form of an executive software program. NC machine: responds to programmed signals from the machine control unit and manufactures the part. CNC系統(tǒng)中常見的組成部分如圖 11所示。 機床控制單元：生成、存儲和處理 CNC程序。機床控制單元還包括機床運動控制器，該控制器是一個可執(zhí)行的軟件程序。 NC機床：響應(yīng)來自機床控制單元的程序信號并對零件進(jìn)行加工。 TextTextFig 11 Components of modern CNC system 現(xiàn)代 CNC系統(tǒng)的組成 of CNC e
