Abstract

PURPOSE:To perform working of high accuracy free from shear droops and burrs by adhering thin films of a thermoplastic resin on both front and rear surfaces of the work, and irradiating a laser beam on the front surface of the work through said thin films. CONSTITUTION:If the work 6 and thin films 11A, 11B are cut simultaneously by a laser beam, the beams of the area of the beam DR-DC making no direct contribution to cutting are absorbed by the film 11A, and the shear droops and burrs in the cut part of the work are decreased. On the rear surface, the film 11B removes the dissolved matter trying to stick on the rear surface of the work 6 efficiently by the vapor generated at the time when it is evaporated by the laser beam, whereby the working producing no burrs on the rear surface is accomplished.
