20090095723 | LASER PROCESSING METHOD - The present invention relates to a laser processing method capable of arbitrarily controlling a concentration distribution of an assist gas supplied for an object having a complicated surface, together with a laser beam. In the case of laser-processing a tape-shaped cord including several coaxial cables, the method is applied for cutting ground lines surrounding each coaxial cable. Prior to a laser irradiation, at the tip portion of the cord, a flow pathway for the assist gas is ensured between the coaxial cables by removing the resin covering each surface of the coaxial cables. Since each coaxial cable has a non-flat shape, a first surface domain, on which the laser beam is incident at an approximate right angle, and a second surface domain, on which the laser beam is incident at a smaller angle, exist in each surface of the coaxial cables. The second surface domain constitutes part of a wall of the flow pathway for the assist gas, and therefore the concentration of the assist gas in the vicinity of the second surface domain increases rather than that of the assist gas in the vicinity of the first surface domain. As a result, a sufficient laser processing efficiency can be ensured even in the second surface domain on which a laser processing efficiency remarkably decreases. | 04-16-2009 |
