REVIEW OF CHATTER STUDIES IN COLD-ROLLING

In the past, many different modes of vibration and causes of rolling c hatter have been presented, yet no complete and clear picture of the b asic mechanics emerged. In order to control chatter in cold rolling op erations, a much better understanding of the basic mechanics of the pr oblem is required. To provide, therefore, a ground work for developing such a basic understanding, in this paper, existing models of a mill stand as well as of the rolling process in the open literature are pre sented. In addition, existing chatter models, which are formulated to investigate chatter as the consequence of the interaction between the structural dynamics of the mills and the dynamics of the rolling proce ss, are also reviewed.
