Laser beam machining method with interrupt and restart functions

摘要

A method for irradiating a workpiece making a relative move in accordance with a work program with a laser beam for cutting the workpiece includes steps of interrupting the cutting being executed and then restarting the cutting. As the cutting is restarted, machining of the workpiece is performed under specified conditions for a predetermined distance and a predetermined time to provide sufficient machining of the workpiece.
