摘　　要：本文对金属切削中不同切削速度情况下刀具前角对切削振动的影响做了大量的实验,并进行了相应的理论分析。其结果表明:随着刀具前角的增加,切削加工振动的振幅逐渐减小:当刀具前角γ_0<0°时,其单向最大振幅发生在v=50～70m/min,当γ_0≥0°时,其单向最大振幅发生在v=160～180m/min。同时还对高速精加工时如何避开振幅最大区域,确保加工质量问题提出了防范措施。Both the theoretical analyses and many experiments about the effect of the cutting tool's rake angle on the cutting vibration at different cutting speed during the process of the metal cut have been made.The result shows that when the rake angle of cutting tool increases, the oscillation of the cutting vibration decreases gradually. When the rake angle γ_0<0°, the maximum oscillation in one direction takes place at the speed of 50～70m/min; When the rake angle γ_0>0°, it takes place at the speed of 160～180m/min. Meantime, measures to keep the amplitude from the region of the maximum oscillation have been put forward so as to ensure the quality of the cutting work.
