Acoustic emission for process control and monitoring of surface integrity during grinding

Summary This study suggests that acoustic emission sensing may be a useful tool for controlling the grinding process, and the following observations can be made: fluid coupling to the grinding zone is easy to implement and is effective; AE is superior to force for detecting wheel/work contact at start of cycle; using RMS signal processing may result in the loss of important surface cracking and contact data; most AE sensors distort the signal from the process but deconvolution can restore the signal; normal force/AE ratio shows a good correlation with cross-lay surface roughness.
