Abstract

A method of obtaining balance correction information includes: obtaining first vibration data when a rotating body is rotating at a specific rotational speed without trial cutting being performed; obtaining second vibration data when the rotating body is rotating at a low-range rotational speed lower than the specific rotational speed without trial cutting being performed; obtaining third vibration data when the rotating body on which trial cutting has been performed at a first correction position is rotating at the specific rotational speed; obtaining a first influence coefficient indicating a degree of an effect that the trial cutting has on vibration of the rotating body, using the first vibration data and the third vibration data; obtaining runout information indicating a degree of runout caused by a shape of the rotating body, using the second vibration data; and obtaining balance correction information using the first vibration data, the influence coefficient, and the runout information.
