Abstract: As the demands for weight reduction and efficiency in high-end equipment continue to escalate, carbon fiber reinforced polymer (CFRP) components are progressively advancing towards a new era characterized by large-scale, thin-walled designs. However, the inherent weakness in rigidity and material heterogeneity of CFRP thin-wall components exacerbate dynamic variations in tool/workpiece interactions during machining. This often leads to chatter phenomena, manifesting as vibrations, burrs, and pits on the workpiece surface, ultimately compromising the surface quality of CFRP thin-wall components. In light of these challenges, the current research progress on milling chatter in CFRP is systematically reviewed, encompassing aspects such as its underlying mechanisms, milling force prediction, dynamic parameter identification of components, and chatter suppression techniques. A comprehensive comparison of the advantages and disadvantages of various principles, models, and methods is presented, alongside a summary of potential future research directions in the field of CFRP milling chatter.
