In this study, the marking on samples by using laser marking on the acrylic sheet is examined. The input experiments factors such as Laser power (20-60 W), Laser speed (200-600 mm/s), and Focal Plane Position (five conditions) are selected. These characteristics determine the output of 17 laser marks designed by the design of experiments (DOE) methodology. In this stage, the Response Surface Method (RSM) is used to find the optimization and statistical modeling of the laser marking process. top section width, Cross section Width, and cross section diameter are responses showing the process’s quality. By applying a 50W CO2 laser, the acrylic sheet can achieve the highest values for the Top part of the Specification. By optimizing the laser marking process, a higher degree of process control can be achieved by considering the relative importance of each input parameter. Recent findings indicate that this approach can lead to a 15% improvement in accuracy, a result with significant implications for industrial applications.
