Abstract
A laser machining device includes a scanner head which can scan a laser beam, a movement means for the scanner head, a scanner head control device and a movement control device. In the laser machining device, the scanner head control device controls, based on a machining parameter on a path motion, the scanner head such that the laser beam is scanned in a first direction and a second direction, the scanner head control device includes a distance calculation portion which calculates, from the information of an angle θ formed by a normal to an item to be machined from the scanner head and the direction of application of the laser beam and a focal length, a difference between a desired machining distance and an actual machining distance and based on the result of the calculation, the movement control device corrects the feedrate of the movement means or the scanner head control device corrects the machining parameter such that the desired machining distance and the actual machining distance are made equal to each other.
