1. A machine tool comprising:
- an enclosed machining area that includes a door that remains closed during operation of the machine tool;
a microphone configured to collect sounds generated by the operation of the machine tool in the enclosed machining area; and
circuitry configured toreceive, from an operator of the machine tool, an input of a characteristic of the sounds generated by the operation of the machine tool to be used to extract an abnormal noise part of the sounds generated by the operation of the machine tool;
extract the abnormal noise part of the sounds generated by the operation of the machine tool and collected in the enclosed machining area for output to the operator, the abnormal noise part being extracted in accordance with the characteristic of the sounds input by the operator; and
output only the extracted abnormal noise part of the sounds to a speaker or earphone located outside of the enclosed machining area during the operation of the machine tool, whereinthe extracted abnormal noise part does not include all the sounds generated by the operation of the machine tool and collected in the enclosed machining area.

Abstract
A machine tool that can output an abnormal noise is provided. A machine tool includes: an input unit configured to receive an input of a setting for defining an operation mode of the machine tool; a storage unit configured to store sound generated during a normal operation of the machine tool and acquired in advance; a sound collection unit configured to collect sound in the machining area; a sound selection unit configured to extract a part of sound collected in the machining area in accordance with the setting input for outputting sound to the outside of the machine tool; and a sound output unit configured to output sound extracted by the sound selection unit to the outside of the machining area.
