Mathematical Modeling of the Effect of CO2 Laser Parameter on Shape and Geometry of Polymer Plate
Authors
Abstract
In recent years, the use of polymer-based materials is in almost every aspect of daily life [1]. PMMA can be used in many areas from aircraft to the medical industry with their good chemical stability, high strength, high corrosion and aging resistance, insulation performance, and smooth surface [2]. In this study, grooves were formed on Polymethyl Methacrylate (PMMA) Plates with different scanning speeds with CO2 laser. Since the scan speed of the laser is increased, the interaction time between the laser beam and the material decreases then the amount of energy transferred to the material also decreases. Measurements were made from high-resolution optical microscope images of the grooves created on PMMA. In this study, the distribution of heat energy transferred to the material was modeled mathematically. The change to groove size depending on the laser scan speed is modeled. To validate the mathematical model, the surfaces of the PMMA plate were ablated with different scan speed at constant power. The CO2 laser that has 10600 nm wavelengths and 130 Watts maximum power was used in the ablation.
