A review on chatter stability in thin-wall milling

Aiming at the chatter problems in thin-wall milling,the research progress of regenerative chatter theoretical models of thin-wall milling was discussed firstly in this work.Then,the milling force model,which is the root of the chatter,was discussed in depth,and the advantages and disadvantages of empirical models,finite element models,and analytical models of milling force were comparatively analyzed.Afterwards,the dynamic characteristics of thin-wall milling systems were discussed in detail.The methods of calculating the frequency response function of the tool tip were divided into experimental method,finite element method,and analytical method.The principles,research status,advantages,and disadvantages of these methods were discussed.Frequency-domain methods and time-domain methods for solving stability problems were comparatively analyzed.Related research on chatter stability of micro-milling meso-scale thin-wall was discussed.Finally,the research status and future directions of chatter stability of milling thin-walled parts were summarized and explored.
