PURPOSE:To automate a working stage by cutting a protection material with the laser light energy of a low output in advance, then performing the machining of the metal member with the laser light energy of high output. CONSTITUTION:A hairline working is executed at one side of a metal member 2 and the working surface is protected by the protection material 1 of a vinyl made, etc. until the cutting stage by the laser machining. In case of performing a piercing on the metal member 2 via a laser beam energy, a laser oscillator is first made to a low output with its control and the circular cutting of the protection material 1 is performed. The cutting of the metal member 2 is performed by the laser light energy which is controlled to a high output. Since the protection material 1 is worked in a low output state the generation of a discoloring, etc., is not caused on the surface of the metal member 2 and the protection material 1 is not deposited on the member 2. Consequently there is no need for removing the protection material with a manual work and the automation of the process is made possible. |
