LASER PROCESSING DEVICE, LASER OSCILLATOR DIAGNOSIS METHOD, AND LASER OSCILLATOR DIAGNOSIS PROGRAM

摘要

A laser cutting device includes a laser oscillator, a cutting nozzle configured to irradiate a work with laser light so as to cut the work, and a controller configured to control the laser oscillator and a drive unit configured to move the cutting nozzle. The controller includes a laser output control unit, a diagnosis performance determination unit configured to determine, when the laser oscillator satisfies a predetermined operation condition, based on a cutting program, whether or not the laser oscillator is diagnosed, and a diagnosis function performance unit configured to issue a laser output command for diagnosis of the laser oscillator to the laser oscillator. When the diagnosis performance determination unit determines that the laser oscillator is diagnosed, the diagnosis performance determination unit outputs the laser output command for diagnosis to the laser oscillator.
