1. A laser beam machine comprising:
a laser oscillator that outputs laser beam; a spectroscope on which the laser beam is entered, and that emits the laser beam after splitting the laser beam into machining laser beam and measurement laser beam; a light detector on which the measurement laser beam is entered, and that transmits a detection signal indicating intensity of the measurement laser beam; an emission unit on which the machining laser beam is entered, and that emits the machining laser beam to a workpiece; and a control unit that is connected to the laser oscillator, the light detector, and the emission unit, wherein the control unit transmits an output signal for starting an output of the laser beam at a first time point and stopping the output of the laser beam at a second time point which is later than the first time point, to the laser oscillator, wherein the control unit receives the detection signal indicating first detection intensity which is greater than first preset intensity, from the light detector, at a third time point which is later than the second time point, wherein the control unit transmits a drive signal for controlling the emission unit to be driven, to the emission unit, at a fourth time point equal to or later than the third time point, and wherein the control unit transmits a warning signal at a fifth time point equal to or later than the third time point. |
