Determination of the relative position between grinding
Acoustic emission signals on grinding The raw AE signal (AE RAW ) is composed of different high frequencies on different energy levels and is difficult to interpret One of the most employed techniques to extract useful information from AE RAW signals consists in using the root mean square value (RMS) of the AE RAW signals (Hwang et al, 2000)acoustic emission signal makes it to a certain extent insensitive to impulsive events such as cracks and burn on the part, although this kind of parameter carries a lot of useful information (Benett, 1994) In this present work, tests results are presented for ABNT 1045 steel and aluminum oxide grinding wheel; setup employed; and tests offPaulo R Aguiar et al InProcess Grinding Monitoring
