PURPOSE:To obtain a method for cutting with laser beam and device therefor to realize a high quality cutting without generating a rough cutting surface by eliminating the stagnation of molten matter at a lower part of the cutting surface of a work to be cut. CONSTITUTION:Cutting is executed while vibrating the irradiating position of a laser beam 1 or the irradiating diameter against the work 6 to be cut during cutting, in order to perform the cutting, a moving means 9 which relatively moves the work 6 to be cut and the laser beam 1, a beam diameter regulating means, or a changeover means is provided. |
