Abstract: A mechanical vibration machining apparatus or the like is suitable for forming a stable machined surface. A mechanical vibration machining apparatus performs machining of a machining target using a horn. A control unit instructs the horn to perform a mechanical vibration operation and a rotational driving operation. The control unit controls the mechanical vibration and/or the rotational driving in a periodic manner. For example, the control unit supports intermittent alternating control. That is to say, when one from among the mechanical vibration and the rotational driving is provided, the other is suspended. Such periodic control allows the stress that occurs due to the applied force to be dispersed, thereby allowing a stable machined surface to be formed.
