Abstract

PURPOSE:To obtain stable shape in machining through removal or fusing of a rise formed around the portion of the workpiece machined with a laser beam irradiated thereon at a power density below the evaporation threshold value of the workpiece after removal machining is accomplished with a laser beam converged and irradiated thereon.
