Title:
LASER MACHINING METHOD
Document Type and Number:
Japanese Patent JP3131357
Kind Code:
B2
Abstract:
PURPOSE: To perform cutting satisfactorily, in the laser cutting of a plate, by removing molten metal stuck to the surface of a work W to be machined at the time of transferring from piercing to cutting.
CONSTITUTION: In cutting a work W by means of a laser beam, in transferring from piercing to cutting, the height of a machining head 3 in the Z-axis direction is gradually raised with the laser output from the laser generator 1 kept constant, and an assist gas is ejected simultaneously, thereby removing molten metal, an obstacle to the cutting process, around the through-hole.
