Abstract
Effect of tool rake angle on cutting vibration by experiments are done at different cutting speed in machining operation, and corresponding theoretical analysis is conducted. Result indicates, amplitude of machining vibration gradually decreases with tool rake angle increasing; while rake angle γ 00°, the biggest unidirection amplitude occurs at V =50~70m/min; While γ 0≥0°, it is at V =160~180m/min. Moreover, quarding measures is presented on avoiding the biggest amplitude range so as to guarantee quanlity in precision machining at high speed.
