This project deals with the basic study of enhancing the                   dynamic stability of cantilever tooling structures such as boring               bars, internal grinding mandrels, and milling cutter used in                    machining.  The damping and stiffness of cantilever boring bars are             increased by using composite structures and by coupling auxiliary               mass with energy dissipative material for the main structure.                        Vibration or chatter experienced in machining using a long,                slender cantilever tooling limits the metal removal rates, reduces              tool life, and effects the finish and accuracy of machined parts.               Manufacturing costs are increased due to additional secondary                   operations required to produce the parts to the desired finish and              accuracy.  Advancements in this area will enable reduction in the               manufacturing costs.
