根据声发射信号特征，用声发射信号判断刀具破损，开发研制出“重型切削刀破损声发射监控装置。”此装置用８０９８芯片为微处器进行振铃计数、声发射信号实时分析处理。当刀具破损或严重磨损时，监控装置发出声光报警信号，并使车床横向退刀．信号响应时间小于１ｓ，其报警成功率达９０％。
According to the characteristics of acoustic emission signal, the acoustic emission signal is used to judge the tool breakage, and a “heavy duty cutting blade acoustic emission monitoring device is developed.” This device uses the 8098 chip as a microprocessor for ring counting and acoustic emission signal real-time analysis and processing. When the tool is damaged or severely worn, the monitoring device emits an audible and visual alarm and retracts the lathe laterally. Signal response time is less than 1s, the alarm success rate of 90%.
