1. A mechanical vibration machining apparatus configured to machine a machining target, comprising:
a horn arranged such that it is pressed in contact with the machining target; and
a control unit configured to control the horn to provide mechanical vibration and rotational driving operation so as to perform the machining,
wherein the control unit is configured to control the mechanical vibration of the horn to be provided in a periodic manner by alternately repeating a first vibration state in which a first mechanical vibration is provided and a second vibration state in which a second mechanical vibration is provided with a level that is smaller than the first mechanical vibration,
wherein the control unit is configured to control the rotational driving operation of the horn to be provided in a periodic manner by alternately repeating a first rotational driving state in which a first rotational driving is provided and a second rotational driving state in which a second rotational driving is provided with a level that is smaller than the first rotational driving,
wherein the control unit is configured to set the horn to the first vibration state during a part or all of the second rotational driving state, and
wherein the control unit is configured to set the horn to the first rotational driving state during a part or all of the second vibration state.
