PROBLEM TO BE SOLVED: To provide a novel and improved laser cutting method and a novel an improved laser cutting device capable of reducing the roughness (sectional roughness) of a cut surface.SOLUTION: The laser cutting method includes converging and applying a laser beam from a torch portion to a target material and scanning the converging point of the laser beam on the target material to cut the target material, and is characterized in that the optical axis of the laser beam is inclined in the moving direction of the torch portion with respect to a reference plane vertical to the moving direction of the torch portion, and a forward inclination angle between the optical axis and the reference plane is adjusted based on the inclination angle of a car front.SELECTED DRAWING: Figure 4 |
