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.

Abstract: An abnormality detection apparatus includes a machine learning apparatus for learning waveform data concerning a physical quantity detected when a machine tool is normally operating. The machine learning apparatus observes the waveform data concerning the physical quantity detected when the machine tool is normally operating, as a state variable indicating a current environmental state, and learns a feature of the waveform data concerning the physical quantity detected when the machine tool is normally operating, using the observed state variable.

The seal structure restricts flowage to the outside of machining fluid through the opening (slot) in a side of a machining tank and has a first seal and a second seal (a seal plate) affixed to the first seal so as to cover the opening. An unevenly shaped part including ridges and grooves extending in the long direction of the first seal is formed on the first seal, and passages are provided that communicate with the groove and the outside to channel the machining fluid drainage path. The first seal may be composed of a plurality of members. A suction device sucks up machining fluid draining from the passages.
