Design of a support system with a pivot mechanism for suppressing vibrations in thin-wall milling

This paper addresses the design process of support systems for suppressing vibrations during thin-wall milling. Supports with point contact and surface contacts are examined under different preloading conditions to understand their effects on the cantilever and torsion vibrations of a cantilever wall. A pivot mechanism is presented that provides a rotation motion to the surface support and damping to the vibration modes. Both impact and milling tests showed that the surface support performs better at suppressing vibrations with the pivot mechanism.
