Design of two - axis controlled damper to suppress vibration of long slim rams

Abstract

The contribution deals with the design of two-axis controlled damper to suppress vibration of long slim rams of larger cross-section. Proposed concept is based on a demand to damp down lowest (bending) eigenmodes of the ram in the X-Y plane. These dominant eigenmodes influence the power transferred to the transfer to the cutting process. Supposed position of the vibration damper body is close to the machining point. The proposed solution of the vibration damper is unique, as it is two-axis version with relatively high action force.
