| 摘 要： | 应用声发射传感器对微铣削过程中的刀具状态进行监测。通过结合传声器传感器，利用小波分析，声发射传感器能更精确有效地监测刀具破损的现象。分别在几种不同的工件材料进行了声发射监测实验。通过该声发射监测刀具破损技术采集得到信号，再利用小波分析对实验数据分析。结果表明，在微铣削中利用声发射信号来监控刀具状态的可行性。

| Abstract: | Acoustic emission (AE) sensors are used to monitor tool conditions in micro-milling operations. Together with the microphone, the AE sensor can detect the tool breakage more accurately and more effectively by applying the wavelet analysis. The processed tool breakage technique by AE sensor is used to perform the wavelet analysis on the experimental data. Results indicate the feasibility of using the AE signals for monitoring the tool condition in micro-milling. |
