Abstract
A machine tool includes a machining chamber, an illuminator in the machining chamber, and an NC unit. The NC unit includes a manual execution unit for executing the machining operation via a pulse signal generated in response to operation of a manually operated part, and has a one-block stop mode in which the NC program is executed for one block and then stopped. A notification unit issues a notification of completion of the execution of one block of the NC program while the machining operation is executed manually using the manual execution unit in the one-block stop mode, and the notification unit includes the illuminator. A change in the illumination state of the illuminator enables an operator to observe the interior of the machining chamber continuously while being notified of the completion of the execution of the one block of the NC program.
