LASER PROCESSING APPARATUS AND METHOD

Abstract: a laser processing apparatus and a laser processing method are disclosed. a laser processing apparatus includes a laser generator configured to generate a laser beam, a scanner configured to process a processing target by radiating a laser output from the laser generator, a moving unit configured to move the scanner, a vision unit configured to capture an image of the processing target processed by the scanner, and a controller configured to analyze a thermal deformation trend of a processing area based on the image of the processing target captured through the vision unit, change a processing recipe based on the thermal deformation trend, and control at least one of the laser generator, the scanner, and the moving unit according to the changed processing recipe.
