Abstract: A vibration absorber assembly which includes a cantilever beam component having a proximal end and a distal end, wherein the cantilever beam component extends along a longitudinal axis between the proximal end and the distal end. A distal support element supports the distal end of the cantilever beam component, and an absorber mass is movable in at least a radial direction with respect to the longitudinal axis. First and second support media support the absorber mass with respect to the cantilever beam component. The first support medium contacts the cantilever beam component at a first support region of the cantilever beam component, and the second support medium contacts the cantilever beam component at a second support region of the cantilever beam component, the first and second support regions being located at different longitudinal positions along the cantilever beam component. Other variants and embodiments are broadly contemplated herein.

Abstract: A toolholder includes a cutting tool mounted to a head attached to a collar at a first end of the toolholder. A shank is located at a second, opposite end of the toolholder. A central cavity extends inwardly from the first end toward the shank. A passive vibration absorber assembly is disposed within the central cavity. The passive vibration absorber assembly includes an absorber body and an absorber cap attached to the absorber body. The absorber body has a first end, a second end opposite the first end, and one or more cavities formed in the second end. The one or more cavities of the absorber body are partially of wholly filled with metal or ceramic particles or powders to provide particle damping for suppressing vibration of the toolholder.

Abstract: A toolholder includes a cutting tool mounted to a head attached to a collar at a first end of the toolholder. A shank is located at a second, opposite end of the toolholder. A central cavity extends inwardly from the first end toward the shank. A viscous fluid inertia mass damper is disposed within the central cavity. The viscous fluid inertia mass damper includes an absorber body having a first end, a second end opposite the first end, a fluid reservoir formed in the damper body for containing a viscous fluid, and a plurality of apertures formed in the damper body for allowing the viscous fluid to flow from the fluid reservoir and through the apertures to suppress vibration of the toolholder. A method for suppressing vibrations in a toolholder is also disclosed.
