This paper presents the experimental investigation on the damping characteristics of turning tools. Especially, the effects of clamping load and surface topography are discussed. Both damping coefficients of normal and tangential vibrations to contacting surface at tool shank are controlled by the slip state at tool shank. When the clamping load is low, a macro-slip between tool shank and tool holder occurs and large damping capacity is obtained. When the clamping load is high, a micro-slip occurs and damping capacity of the tool is reduced a little. Latter state of damping is important for real engineering operation. The explanation of these damping capacities is carried out from the point of surface contact with micro-asperities.
