Effects of the clamping conditions of disc-type tools, such as circular saws for wood cutting, on bending deformation and damping characteristics are examined in a model experiment. The clamped part at the center is regarded as a thin disc on an elastic foundation. The differential equation of bending deformation is solved, considering the elastic deformation effect at the clamped part, and the circumferential deflection in the thickness direction is clarified as a function of disc size and clamping conditions. Combining this result with the measured value of disc circumferential deflection, the experimental equation for estimating contact rigidity at the clamped part is obtained, and the parameters which exert an influence on the contact rigidity are clarified. Furthermore, the damping capacity for the fundamental vibration mode is clarified as a function of clamping conditions.
