Document Type and Number:
Japanese Patent JP4143607
Kind Code:
B2
Abstract:
A laser irradiation device and a method thereof for irradiating a laser beam onto a workpiece for bending processing are disclosed. The laser irradiation device includes a light condensing unit configured to condense an incident laser beam; a shaping optical unit configured to change the condensed laser beam from the light condensing unit to a laser beam having an elongated elliptic cross section, and irradiate the shaped laser beam onto the workpiece; and a control unit configured to adjust a relative position between the shaping optical unit and the workpiece so that a long axis of the cross section of the shaped laser beam is in coincidence with a reference line on the workpiece.
