At the beginning of the CNC machine tool, the aircraft parts with complex profile are selected as the machining object, which is the key to solve the problem that ordinary machining methods are difficult to solve.
The most important feature of CNC machining is that the machine tool controlled by perforated tape (or magnetic tape) is used for automatic machining. Because aircraft, rocket and engine parts have different characteristics: aircraft and rocket parts and components have large dimensions and complex surfaces; Small size and high precision of engine parts and components. Therefore, the CNC machine tools used by aircraft, rocket manufacturing departments and engine manufacturing departments are different. In aircraft and rocket manufacturing, large-scale CNC milling machines with continuous control are mainly used, while in engine manufacturing, both CNC machines with continuous control and CNC machines with point control (such as CNC drilling machines, CNC boring machines, machining centers, etc.) are used.
