Ultra-high-speed milling is a high-performance method of processing metals with a blade tool that ensures high surface quality and accuracy. In the presented work, based on the analysis of chip formation processes, as well as thermal and dynamic phenomena occurring during ultra-high-speed cutting, a decrease in roughness and waviness of the treated surface, along with a reduction in the size and degree of the riveted layer, is noted. The justification for increasing the stability of movement during cutting is provided, taking into account the specific features of the ultra-high-speed machining. It is shown that ultra-high-speed milling offers more stable machining conditions, which leads to a decrease in the deviation of the shape and dimensions of the processed parts, consequently increasing accuracy. This makes it possible to eliminate operations such as grinding and polishing and reduce the number of metalworking equipment needed.
