摘　　要：提出了融合声发射信号和电流信号检测刀具破损状态的方法，尤其是采用小波变换处理电流信号获取信号特征，可以改善检测系统的适用性。实际应用证明系统具有高的可靠性。In this paper, the method of detecting tool breakage using the fusion of AE signal and current signal is presented, and the signal features are extracted by current signal wavelet transform which improves the system availibility. Practical applications show the system is of high reliability.
