High-speed ball-end milling is widely used in the field of the molds and dies manufacture, the mold surface quality relates to product quality and mold life. The nature of the mechanism of high-speed ball-end milling surface summarized as follows: Unbalanced periodical milling force and temperature field affected on the elastic-plastic materials surface, which produced elastic recovery and the deformation of machined surface, and changed the features of the workpiece geometry precision and mechanical proper...
