Review of research on chatter stability in milling of thin-walled parts

Milling is widely used in the processing of thin- walled parts with weak rigidity. As the chatter during the milling of thin-walled parts will cause processing quality problems, some measures need to be taken to suppress chatter. This paper describes the research overview of chatter stability during milling. According to the physical conditions of flutter formation, flutter can be divided into vibration-type coupled flutter, friction-type flutter, and regenerative flutter. In order to solve the problem of flutter, the flutter is firstly modeled dynamically, and then the flutter model is solved by the frequency domain method, the discrete method, etc., and the stability domain lobe diagram can be drawn. In addition, the research on flutter prediction, flutter stability analysis, flutter monitoring and flutter suppression is summarized and analyzed. The research and methods on the flutter problem are continuously proposed, which effectively promotes the processing efficiency and surface quality of thin- walled parts.
