The present invention relates to a machine tool, a feedback control method for controlling the rotational speed of a spindle on which a tool is mounted, and a storage medium in which a computer program is stored. The machine tool is provided with a control device for performing feedback control on the rotation speed of a spindle on which a tool is mounted. The control device is provided with: an acquisition unit that acquires the circumferential position of the spindle; and a creation unit that creates a gain correspondence map, the gain correspondence map showing the relationship between thespeed loop gain related to the rotation of the spindle and the circumferential position of the spindle. The control device controls the rotational speed of the spindle on the basis of the circumferential position of the spindle acquired by the acquisition unit and the gain correspondence map created by the creation unit. 本发明涉及机床、反馈控制方法以及存储介质，所述机床和反馈控制方法用于对安装刀具的主轴的旋转速度进行控制，所述存储介质存储有计算机程序。机床具备对安装刀具的主轴的旋转速度进行反馈控制的控制装置。控制装置具备
