1. A machine tool capable of machining a workpiece, the machine tool comprising:
a first discharge unit that discharges a coolant removing a chip of the workpiece;
a portion inside the machine tool and to which the coolant should not be discharged;
a first drive unit that changes a relative position between the first discharge unit and the portion by moving at least one of the first discharge unit and the portion; and
a control unit that controls the machine tool,
wherein the control unit performs
processing for recognizing a position in the machine tool of a moving object by the first drive unit between the first discharge unit and the portion, and
processing for controlling the discharge of the coolant by the first discharge unit such that the coolant is not discharged to the portion based on the position recognized in the recognition processing.
