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 its 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
withCO2laser. 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 130Watts maximum power was used in the ablation.
