Abstract
Provided is a measuring method for measuring laser scanning velocity for a laser beam machining apparatus. The laser beam machining apparatus includes a mirror, and is configured to process a work by irradiating laser. The laser is irradiated by operating the mirror. The measuring method includes measuring processing sound of the work by the laser using the laser beam machining apparatus. Further, the measuring method includes calculating scanning velocity of the laser by analyzing a frequency of the measured processing sound using the laser beam machining apparatus.
