Factors Affecting the Depth in CO2 Laser Engraving for Acrylic Material (Case Study)

Abstract

The aim of this study is to investigate the capability of surface engraving technology for acrylic materials. The study uses CO₂ laser engraving and cutting machine engraving technology. The study encompasses a cutting speed of 3,600-6,000 mm/min and a laser power of 60-120 W. The distance (gap) between the laser cutting head and the surface of the workpiece is 4.2-5.0 mm. We measure the size of the engraving groove. The results are based on the average of the minimum engraving groove depth. We also analyze the surface roughness quality of both the carving groove and the workpiece surface in detail. The results indicate that the acrylic material has an average surface roughness. By adjusting the cutting speed, the carving groove area is 1.965 µm, and the surface area of the sample is 1.403 µm using the cutting speed of 6,000 mm/min, laser power of 120 W, and distance between the laser cutting head and the workpiece surface of 4.8 mm.
