A review of chatter suppression in thin-wall milling: strategies, mechanisms, and applications
International Journal of Extreme ManufacturingThin-walled parts have been widely employed as critical components in high-performance equipment due to the high specific strength and light weight. However, owing to their relatively weak rigidity and poor damping properties, chatter vibration is likely
