Title:
LASER PROCESSING METHOD AND LASER PROCESSING APPARATUS
Document Type and Number:
Japanese Patent JP2012192420
Kind Code:
A
Abstract:
To provide an efficient laser processing method capable of executing laser ablation of a hard-to-work material such as a fiber reinforced composite material or the like, and realizing the industrially satisfactory processing speed, and to provide a laser processing apparatus used therefor.
In the laser removing operation for removing a laser beam irradiation part by irradiating, with laser beam, a surface of a workpiece consisting of a fiber-reinforced composite material or an inorganic material which is hardly machine-cut, a removing means for removing decomposition products generated by laser beam irradiation simultaneously with the laser beam irradiation is used. The removing means is a nozzle for jetting fluid to the laser beam irradiation part at the pressure of 0.3-5.0 MPa.
