摘要
In order to apply laser processing to advanced material mold making, basic research is carried out. First, box-shaped hole processing is carried out by laser beam scanning. Second, suitable machining conditions are investigated in terms of laser spot size, scanning path, scanning speed and scan times. Finally, the comparison of nano- with femto-second laser-processed surfaces is carried out. The laser-processed surfaces and debris are observed with a scanning electron microscope (SEM) and a laser microscope, and are also analyzed using an electron probe microanalysis (EPMA), an X-ray diffractometer and a Vickers hardness tester.
