Abstract
A laser-emitting head (12) is placed in a cavity (6) of an aluminum hollow and profile material (3), the material being of a desired shape in cross section and having an inner peripheral wall. A laser beam of an energy level capable of cutting the material is irradiated from the cavity onto the inner peripheral wall while the head is being rotated along the wall in a circular direction. The hollow and profile material (3) can be sliced in this manner to produce knuckles (1) as one of automobile parts, even if it is of a comparatively large size adapted for production of larger knuckles.
