In the previous papers, the principle of a vibrationless forging hammer was proposed, and optimum design procedures of the feedforward control system were shown. The purpose of this paper is to realize the vibrationless system designed by feedforward control method and also to verify the capability of the system experimentally. First, before making impact experiments of the system, this paper adopts a feedforward chart proposed by the authors to estimate the control effect as well as to determine the realizability of the control system. Then, from a viewpoint of impact experiment, the control effect of suppressing the impulsive force is shown. Furthermore, it is demonstrated that both analytical and experimental results show a high degree of agreement. Finally, by changing impact conditions such as the height of a hammer head, impact numbers, etc., the robustness of the control system is shown.
