One of the major obstacles to raising the work efficiency of the machining process using a machine tool in the past was the phenomenon of chattering. Several factors are conceivable as the causes of chattering. It is generated, first of all, by extremely unfavorable dynamic stiffness in the structure of a machine tool. Numerous active dampers have been announced for improving the dynamic stiffness of the structure of machine tool. A Quasi-Moment Damper differs from previous methods in that attention is paid to the bending moment as a control quantity. This paper includes the experimental results and theoretical analysis of a ram provided with a quasi-moment damper.
