若光束能量足夠高就會將材料穿透。切割絲在兩個導輪之間拉緊,像帶鋸一樣切割工件。TextText Turning centers with increased capacity tool changers are also making strong appearance in modern production shops. These CNC machines are capable of executing many different types of lathe cutting operations simultaneously on rotating part. 具有大容量刀庫的車削中心在現(xiàn)代制造廠中占據(jù)著顯著位置。這種托盤系統(tǒng)用來自動裝卸工件。 NC機床:響應來自機床控制單元的程序信號并對零件進行加工。因此,我們可以通過對計算機進行編碼從而在加工時實現(xiàn)機床操作的各種功能。 NC機床的控制單元通常由硬件構成,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。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
