Special Issue Information

Dear Colleagues,

Since the advent of the laser in 1960, laser materials processing has occupied an important role in the manufacturing industry and economy. To date, laser manufacturing technologies encompass micromanufacturing technology (e.g., surface engineering, welding, cutting, marking, laser additive manufacturing), micromanufacturing technology (e.g., precision cutting and drilling, laser ablation), and micro/nanomanufacturing technology (e.g., femtosecond laser direct writing, two-photon polymerization, laser-induced surface micro/nanostructures). Laser manufacturing has become an outstanding processing technology in advanced manufacturing. As such, with the continuous evolution of the traditional manufacturing industry, new requirements have emerged for the fast-growing field of laser manufacturing.

This Special Issue, “Advanced Technologies in Laser Materials Processing”, seeks high-quality works focusing on cutting-edge research in laser materials processing. Topics of interest include, but are not limited to:

  • Modeling for laser materials processing;
  • Advanced laser processing;
  • Laser applications;
  • Laser-based additive manufacturing.

In this study, the laser cutting characteristics were analyzed according to the shape of the back side of the specimen, and the laser cutting characteristics were compared according to the thickness of the edge (10 mm, 20 mm, and 30 mm). A Yb-YAG laser was used in this study, and the cutting target was STS304 with a thickness of 50 mm, and the cutting process was analyzed using a high-speed camera. In the experiment, it was found through image analysis that the cutting performance was excellent at 30 mm thickness of the edge. In order to analyze this reason, a thermal conduction analysis (numerical simulation) was performed, and it was confirmed that the thicker thickness of the edge caused a preheating effect during laser cutting due to a large amount of heat accumulation. This effect can be used as a reference for the initial processing state while cutting thick metals as it is a characteristic that has not been revealed before. Full article
