Tuning vibration absorbers to mitigate simultaneous regenerative and mode-coupling chatter

This paper examines a set of parametric tunings for vibration absorbers to enhance stability in the event simultaneous chatter during machining and proposes novel tuning criterion minimizing definite integral frequency response function, while accounting damping absorber’s base component. Chatter vibrations are an inherent characteristic processes, common tool mitigating is tuned mass damper (TMD), which functions effectively when its dynamic characteristics appropriately natural vibrating Robotic recent cost-effective method material removal, but regenerative mode-coupling can arise on robot tools. TMD criteria different, suppress one may prompt other. Moreover, conventional analytical do not consider component, be valid assumption low-damped machine tools highly-damped The possibility component effect necessitates exploration alternative criteria.
