The article considers Scientific and technical approaches to the problem of determining the cutting speed during machining of the working surfaces of machine parts and products with a unified tool on CNC lathes. It compares the optimum cutting temperatures obtained during turning of steels with the temperatures of their structural phase α–γ transformations. It is shown that the law of constancy of the optimum cutting temperature ensures the maximum tool life, the highest machining accuracy at the optimum cutting speed, both for structural and hard materials.
