[0002] Metal processing is the process technology of processing metal materials into various items, parts or components, covering the manufacture of large structures to precision components. Metal processing not only occupies an important position in industrial production, but is also the foundation of modern manufacturing industry. Milling cutter is an important metal cutting tool used for metal processing of various shapes and sizes on milling machines. Milling cutter is a rotating tool with one or more teeth. It intermittently cuts the excess on the workpiece through the teeth to process the required shape. They are mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines. For example, ball-end milling cutters are usually used to process complex curved surfaces, while flat-end milling cutters are suitable for processing planes or simple inclined surfaces. Depending on the material, the milling cutter can be made of high-speed steel, tungsten carbide or other cemented carbides to adapt to different cutting speeds and processing conditions. Choosing a suitable milling cutter is crucial to improving processing efficiency and ensuring processing quality.
