DAMPING CHARACTERISTICS OF AN IMPACT DAMPER AND ITS APPLICATION

In this study, in order to improve the damping capability of long, thi n cutting tools, such as boring tools or drills, an impact damper with the following features was developed: small and simple in constructio n; easy to mount on the main vibratory systems; and no need to adjust parameters of an impact damper to the vibratory characteristics of the main vibratory systems. Using this impact damper, the characteristics of the impact damper were investigated in detail when the main vibrat ory system was vibrated in the direction of gravity and perpendicular to it. Furthermore, application of the impact damper to improve the da mping capability of drills was attempted.
