Abstract

A machine tool has a cover that prevents chips generated by machining and cutting fluid from scattering around and a plurality of movable nozzles with liquid discharge directions thereof being movable so as to wash out chips that have adhered to or accumulated on an inner surface of the cover. The machine tool is capable of changing a discharge direction of each of the movable nozzles individually. The machine tool compares the state of the inside of the cover before start of machining with the state of the inside of the cover after chips are generated to determine an adhesion or accumulation state of chips. The machine tool thus calculates the liquid discharge direction to wash out chips from the movable nozzles based on a result of the determination.
