The present invention relates to a laser marking method for marking a desired pattern by irradiating a laser beam onto a curved part included in a workpiece comprising a dividing step, a rotating step, and a radiating step. In the dividing step, a curved part is divided into multiple sub-curved parts having a predetermined central angle based on the center of the radius of curvature of the curved part. In the rotating step, a workpiece is rotated as much as the central angle of the sub-curved part in order for the sub-curved part to face an optical axis of the laser beam. In the radiating step, the sub-curved part is irradiated with a laser beam. According to the present invention, a laser marking method is capable of continuously marking a desired pattern to a curved part by alternately and repetitively performing the rotating step and the radiating step. |
