Stability Limit of Regenerative Chatter in Cylindrical Traverse Grinding

Abstract

Self-excited vibration in cylindrical plunge grinding caused by the regenerative effect of workpiece surface has been investigated by many researchers. But there are very few reports about cylindrical traverse grinding. In this paper, self-excited vibration in cylindrical traverse grinding caused by the workpiece regeneration is theoretically investigated and their results are compared with the experimental results. It was proved that regenerative chatter may very possibly occur under the following conditions, i.e., low traverse velocity, high workpiece velocity, wide grinding width and small depth of cut. And those results are confirmed by the experiment.
