Experimental Reasearch on Grinding Surface Waviness of Engineering Ceramics

In this paper, an experiment has been made to take vibration and surface waviness of two kinds of engineering ceramics ( zirconia ceramics and alumina ceramics) as research targets. The experimental research results show that two kinds of surface waviness are on the workpiece, one is sparse and the other one is dense. It is known that the sparse one is caused by the forced vibration. In order to find out the generation mechanism of the dense one, a further exploration has been made. It shows that the dense surface waviness is caused by the self-excited vibration. Finally, some methods are put forward to reduce the surface waviness.
