AE-based monitoring of grinding wheel dressing
Currently, a conventional grinding process requires a complex sequence
of tasks in order to start production on a workpiece, including
equipment setup, machining of initial test samples, calibration of
the tool, and frequent control and correction of the process parameters.
AE can serve as a means for the complete automation of all
these steps184. However, in grinding, the two main limitations of
AE-based monitoring solutions are the oscillation of the RMS level
and signal saturation. Despite these limitations, AE can be very effective
for contact detection between moving surfaces. The following
section will focus on a Fast AE RMS analysis and mapping
technique for wheel condition monitoring in grinding.
