Abstract: With the rapid development of manufacturing, laser cutting technology, as an advanced processing method, has been widely used in the field of sheet cutting. This article mainly studies the laser cutting process of 3 mm thick carbon steel sheet, and analyzes the influence of process parameters such as cutting speed, auxiliary gas pressure, and focus position on cutting quality through experimental methods. The experimental results show that appropriate cutting speed and auxiliary gas pressure can improve the quality and efficiency of cutting, while optimization of focus position can further improve the quality of cutting section. These findings are of great significance for guiding practical production and improving the process level of laser cutting for thin sheets.
