This study focused on the effect of processing parameters of CO₂ laser on kerf width and depth
of basalt fiber reinforced epoxy composite. In this research, the Taguchi method has been followed to
optimize the laser power, scanning speed, and frequency for minimum thermal damage and a maximum
rate of cutting. Laser parameters resultant in nine different experimental combinations were studied. The
obtained results showed that, in general, an increase in the laser power led to larger and more profound kerf
structures, while an increase in the scanning speed worked oppositely. For example, at 20 W with a speed
of 100 mm/s and frequency with 5 kHz, the interaction without apparent material removal gave place to a
narrow and shallow kerf. In this case, when increasing the power to 45 W and the speed of the process to
100 mm/s, the kerf that was obtained was very much wider and deeper to a minimum depth of 130 m.
Higher laser frequencies resulted in increased energy accumulation on the material surface; hence, this
showed greater material removal and greater depths during kerf formation. The range for optimum balance
between kerf width and depth was for a power of 45 W, speed of 200 mm/s and frequency of 50 kHz. This
gave a reasonably deep and wide kerf with less thermal damage. These results have further established
guidelines that could be useful in the optimization of laser processing for basalt composites for applications
involving fine material removal and surface texturing.
