Behavior of tool system which consists of one degree of freedom mass-spring system is characterized by repetitive steady-state motion for impact working like as hammering, punching and press. The self-excitation is applied to improve motional stability for the workings. The tool motion don't have an effect on fine variation of working condition by means of the self-excitation which makes to act pull up and down excitation forces between pre-setted switch on and off positions, respectively. Then, the steady-state repetitive working motion is absolutely stable over the all drive condition. In the case that the pull up force cut time comes nearer at working start time and switch on time of the pull down force comes nearer at time of leave from a workpiece, the both force levels required for an arbitrarily decided initial working velocity approach to the minimum values. If switch on time of the pull down force comes near by the center of period of the motion, the required force level has the minimum value regardless of addition of the pull up force in the light damping.
