Abstract
A laser cutting apparatus includes a laser oscillator; an output control unit for a laser beam; a cutting head configured to emit the laser beam; a gap sensor; an axial mechanism configured to activate the cutting head; an axial control unit; a detection unit configured to detect reflected light intensity; a storage unit configured to store an output value of the laser beam, reflected light intensity, a detection value of the gap sensor, and positional information of the axial mechanism; and a correlation table generation unit configured to output an instruction to operate the axial mechanism and the laser oscillator, and generates a correlation table configured to obtain a correlation between the output value of the laser beam and the reflected light intensity, a correlation between the positional information and the reflected light intensity, and a correlation between the detection value and the positional information.
