Abstract
In this paper, the design and testing of a tuned holder that increases the dynamic stiffness of boring bars is described. By matching the holder natural frequency to the clampedfree boring bar natural frequency, a new dynamic system is obtained with decreased vibration magnitude and reduced susceptibility to chatter. In this approach, the flexible holder supports the boring bar and effectively acts as a dynamic absorber for the clamped boring bar. Design trends are explored using an analytical receptance coupling model and experimental validation is provided.
