CO2 laser engraving and cutting machines is often popular among creative artists. The machine's ability to form logos, text, drawings, and much more allows artists to produce more complex artwork quickly. CNCKB Industry (CNCKB), a local machine manufacturer, has successfully produced several models of this machine to meet demand. However, research on the ideal parameters based on the workpiece material used and the cutting accuracy produced using this machine is limited. This study aims to identify the ideal parameters for cutting plywood and acrylic of different thicknesses and to determine the accuracy of the cutting results. A powerful 80W CO2 laser engraving cutting machine was used to conduct this study. Basic circular shapes with diameters of 10 mm, 20 mm, 30 mm, 40 mm, and 50 mm were cut from 3 mm and 5 mm thick plywood and acrylic workpieces. The study findings indicate that the ideal cutting parameters for 3 mm plywood are a laser head speed of 20 mm/s with a laser power of 30%. For 5 mm thick plywood, the ideal cutting parameters are a laser head speed of 25 mm/s with 50% laser power. For acrylic workpieces, the ideal parameters for cutting 5 mm thick material are a laser head speed of 5 mm/s with 50% laser power. Meanwhile, for 3 mm acrylic, the laser head speed is 10 mm/s with a laser power of 30%. The study findings also show that the cutting accuracy for both materials is within a difference range of 97% to 99.7%. In conclusion, the ideal parameters for cutting plywood and acrylic materials depend on the thickness of the workpiece and the type of material used. Additionally, the cutting accuracy using the machine produced by CNCKB is in the range of 97% to 99.7% of the desired dimensional size.
