Abstract
The laser machining apparatus includes a transmission fiber that transmits laser light emitted from a laser oscillator through the fiber, a machining head that emits the laser light, which is sent from the transmission fiber, vertically to a main surface of a machining object and sends reflected light, which is reflected coaxially with the laser light by the machining object, to the transmission fiber, a reflected light monitoring unit that detects a reflected light intensity of the reflected light sent from the transmission fiber, and a control device that controls the laser oscillator and the machining head, in which the control device includes a determining unit that, at a time when laser machining is started, determines whether the machining object corresponds to a machining condition or not in laser machining on the basis of the reflected light intensity.
