摘　　要：建立了基于铣削噪声的刀具状态监控系统,以研究铣削过程中不同主轴转速、进给速率对刀具磨损状态的影响。试验表明,在2kHz^3kHz频率范围内,切削噪声与刀具磨损有着很好的相关性。在给定加工条件下,该系统能有效识别和预测刀具磨损状态。An on-line tool flank wear＇ s condition monitor system is established. Based on this system, the influences of a variety of different cutting speeds and feed rates can be analyzed. The experimental results indicate that the cutting noise and the tool flank wear have a well pertinence in the frequency domain between 2kHz - 3kHz. It is concluded that in the given working circum- stance, the monitor system of tool condition through cutting sound emitted could effectively identify and forecast the tool＇ s flank wear condition.
