The frequency characteristics of the workpiece at cutting on the lathe were investigated using the impulse technique. The natural frequencies and damping ratios of the workpiece at cutting were greater than those at no cutting. The damping ratios decreased with an increase in the cutting speed. The estimated natural frequencies, which were calculated from data of the static cutting experiments, were smaller than those of the dynamic experiments, and the estimated damping ratios larger than those of the dynamic experiments. The reason for decrement in the frequencies and increment in the damping ratios was considerd to be the difference of the shear angle between the static and dynamic conditions. The dynamic shear angle was smaller than the static one. The cutting process was expressed in the first order system which became the lead or lag factor.
