Abstract
In a laser machining device, a laser emitter is inhibited from emitting a laser beam in a stop state, and can emit the laser beam in a machining state. A controller is configured to perform: in response to detecting opening of a door of a machining chamber, bringing the laser emitter into the stop state and disabling receipt of a release command via an interface; in response to detecting closing of the door while the laser emitter is in the stop state, determining whether the laser emitter is in the machining state when the opening of the door is detected; in response to determining that the laser emitter is not in the machining state, releasing the stop state of the laser emitter; and in response to determining that the laser emitter is in the machining state, enabling the receipt of the release command via the interface.
