High-speed machining;  processing parameters;  knives;  Mold

The significance of the application of high-speed machining technology in mold manufacturing is described, and some core technologies necessary to achieve high-speed machining are described. By comparing with conventional EDM methods, the superior performance of high-speed machining and the requirements of high-speed machining for the spindle, tool and CAM software of machine tools are discussed, and it is pointed out that in the cavity mold manufacturing process, the choice of machining method mainly depends on the geometry of the cavity, the hardness of the material and the required process parameters, and finally the processing example shows that high-speed cutting is one of the development directions of modern mold processing.
