[0002] Laser technology is developing rapidly, and laser cutting equipment is one of the most important applications in the laser processing industry. Laser cutting equipment uses a high-power-density laser beam to irradiate the material being cut, rapidly heating it to its vaporization temperature and causing it to evaporate and form a hole. As the beam moves across the material, the hole continuously forms a very narrow kerf (approximately 0.1 mm), completing the cutting process. Compared to other cutting methods, the biggest difference in laser cutting equipment is its high speed, high precision, and high adaptability. It also offers advantages such as good cut surface quality, low noise during cutting, fine kerf, and low pollution. Therefore, laser cutting equipment is widely used in various industrial production sectors.
