This paper presents an analytical model to characterize the role of an impact damper in suppressing vibrations of slender boring bars that are used in deep hole boring processes. The boring bar is modelled as a Euler-Bernoulli beam that interacts with a ring impact damper through a spring and damper combine. Parametric analysis suggests that smaller gaps in between the bar and the damper result in higher reduction in the vibration response. Analysis also suggests that for maximum vibration suppressions the damper’s stiffness should be less than that of the bar, and its damping should be greater. Though the vibration suppression capacity of this impact damped boring bar is found slightly wanting when compared to a boring bar damped with an optimally tuned mass damper, model-based analysis as is presented herein is new and generalized and can hence guide further design and development of optimal impact damped boring bars.
