CNC milling is a machining technology that uses a computer numerical control (CNC) system to precisely operate a milling machine. By programming and controlling the toolpath, it can efficiently complete the machining of complex parts. Compared with traditional manual machining, CNC milling has advantages such as high precision, good repeatability, and a high degree of automation.
In the CNC milling process, the operator first needs to use CAD/CAM software to design the part model and generate a machining program (G-code). Then, the machine tool automatically executes the cutting operations according to the program. Common CNC milling machines include three-axis, four-axis, and five-axis machines, with five-axis machines capable of machining more complex spatial surfaces.
