適応ディジタルフィルタを用いた目づまりによる異常状態のインプロセスセンシング

抄録

In this investigation, the output signal of the acceleration sensor attached to the axis of the grinding wheel is directly utilized and adaptively pursued by adaptive digital filter (ADF), whose parameters indicate the signal pattern. The grinding forces are dynamically measured, and discussed compared with the index calculated from the ADF parameters. The entire process of the grinding force in Al-Si alloy grinding consists of three stages of tool wear in sequence. The vibration by the accelerator and ADF distinguish these stages clearly. Thus this method is very efficient for monitoring the loading chips.
