低速稳态切削的刀具耐用度

Cutting Tool endurance of Steady-state in Low Speed

根据切削加工系统的颤振理论，讨论了在低速切削状态下，刀具后刀面的磨损宽度及刀具耐度推导了在低速稳切割下，后刀面磨损宽度及力具耐用度计算的经验公式，从而在低速范围内，给稳态切削刀具耐用度的选择提供了一个理论依据．

According to the theory of vibration of the machining system, the wearing width ofback face and the endurance of cutting tools in low-speed cutting are discussed. From this, the empirical formula used to calculate the steady-state cutting wearing width of back face and the endurance of cutting tools in low speed is derived. The theoretical basis of selecting the endurance ofthe cutting tools in steady-state cutting at low speed is sup￣d
