LASER SURFACE TREATMENT METHOD AND LASER SURFACE TREATMENT APPARATUS WITH RADIATING THE SURFACE TO BE TREATED ALONG AN ACUTE ANGLE

摘要

A laser surface treatment method according to the present invention is a laser surface treatment method for treating a surface of a workpiece (2) having an irregular shape, radiates a laser beam (11) so that the surface of the workpiece (2) which is placed in a direction forming an acute angle with respect to the laser (11) becomes an untreated plane, and scanning with the laser (11) so that the surface of the workpiece (2) which is placed in the direction forming an acute angle with respect to the laser (11) becomes an untreated plane.
