Machine tool, machine tool control method, and non-transitory computer-readable medium

A method for controlling a machine tool capable of machining a workpiece,

• the machine tool including:
• a 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;
• and
• a drive unit that changes a relative position between the discharge unit and the portion by moving at least one of the discharge unit and the portion,
• the control method comprising:
• recognizing a position in the machine tool of a moving object by the drive unit between the discharge unit and the portion;
• and
• controlling discharge of the coolant by the discharge unit such that the coolant is not discharged to the portion based on the position recognized in the recognizing.

A non-transitory computer-readable medium storing a control program for a machine tool capable of machining a workpiece,

• the machine tool including:
• a 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;
• and
• a drive unit that changes a relative position between the discharge unit and the portion by moving at least one of the discharge unit and the portion,
• the control program causing the machine tool to execute:
• recognizing a position in the machine tool of a moving object by the drive unit between the discharge unit and the portion;
• and
• controlling the discharge of the coolant by the discharge unit such that the coolant is not discharged to the portion based on the position recognized in the recognizing.
