Abstract
A laser processing apparatus of the present disclosure controls outputs of a blue laser oscillator and an infrared laser oscillator such that before a surface melting is detected on a workpiece, the workpiece is irradiated with at least blue laser light, and after the surface melting is detected on the workpiece, a power of infrared laser light with which the workpiece is irradiated is increased as compared to before the surface melting is detected.
Claims13
A laser processing method comprising:
- a first irradiation step of irradiating a workpiece with at least blue laser light at an initial processing stage before a surface melting of the workpiece;
- a melting detection step of detecting the surface melting of the workpiece;
- and
- a second irradiation step of irradiating, after the surface melting is detected, the workpiece with infrared laser light having a power higher than a power before the surface melting is detected.
1 more element
A laser processing apparatus comprising:
- a laser light former that forms blue laser light and infrared laser light with which a workpiece is irradiated;
- a melting detector that detects a surface melting of the workpiece;
- and
- an output controller that controls a power of the blue laser light and a power of the infrared laser light output by the laser light former,
- wherein the output controller causes the laser light former:
- before the surface melting is detected on the workpiece, to irradiate the workpiece with at least the blue laser light, and
- after the surface melting is detected on the workpiece, to increase the power of the infrared laser light with which the workpiece is irradiated as compared to before the surface melting is detected.
4 more elements
An output control device of a laser processing apparatus comprising:
- an output controller that controls a power of laser light with which a workpiece is irradiated;
- and
- a melting detector that detects a surface melting of the workpiece,
- wherein the output controller controls a power of laser light:
- before the surface melting is detected on the workpiece, to irradiate the workpiece with at least blue laser light, and
- after the surface melting is detected on the workpiece, to increase a power of infrared laser light with which the workpiece is irradiated as compared to before the surface melting is detected.
