Vibration Monitoring of the Internal Centreless Grinding Process Part 2: Experimental Results

Abstract

Experimental results of grinding tests are presented showing how both forced and self-excited vibration occurring during the internal centreless grinding process can be associated with deterioration in workpiece finish and form. Mechanical vibration from rotating machine elements and wear of the dressing diamond and grinding wheel are all investigated. It is shown how a deterioration in these parameters can be associated with characteristic vibration signatures, and a good correlation obtained with the models proposed in Part 1 of this paper.
