Damping capacity of the machine tool is determined by the internal friction of the structural material and the frictional damping of the joint. In particular, improving damping capacity of the joint is known to be highly effective on the improvement of dynamic characteristic of the structure. However, it is generally indicated that the existence of the joint decreases static stiffness of the structure. Therefore, in this study, the method for improving damping capacity of the joint in jointed structures without reduction of static stiffness is experimentally considered. As a result, interfering disk spring at the joint improves damping capacity in jointed structures without reduction of static stiffness.
