目前,国外出现一种在机械加工过程中可听到声音发射的智能刀片,分析声音信号就能监测到刀具开始损坏等不正常的情况。这种智能刀片实际上是一种声发射传感器,它采用新颖的方法,获得金属加工中很强的信号,一种方法是把声发射传感器连接到旋转的铣刀心轴上,传感器悬浮在心轴周围的 At present, a smart blade that can hear sound emission during machining appears in foreign countries, and abnormal signals such as the start of tool damage can be monitored by analyzing the sound signal. The smart blade is actually a type of acoustic emission sensor that takes a novel approach to obtaining a strong signal in metalworking. One method is to attach the acoustic emission sensor to a rotating milling cutter mandrel, and the sensor is suspended on the mandrel surrounding
