近几年来,根据最佳切削温度提出采用最佳切削用量組合,可使切削时的刀具耐用度、加工生产率同时达到最优的水平,又具有較高的加工精度,从而使切削过程实現优化。为在現有机床設备上提高刀具耐用度和生产率提供了切实可行的新途径。而用于难切削材料,其經济效果尤为显著。按最佳切削温度所对 In recent years, according to the optimal cutting temperature, the optimal combination of cutting dosage is proposed, which can make the cutting tool durability and processing productivity reach the optimal level at the same time, and also has higher machining precision so that the cutting process can be optimized . It provides a new and viable way to improve tool life and productivity on existing machine tools. For hard-cutting materials, its economic effect is particularly significant. By the best cutting temperature right
