Wood Laser machining using CO2 30W laser in CW and pulse regime

Aim of this work is to investigate the influence of the process parameters on the material removal rates by engraving panels made of Aframosa wood using a CO2 laser working with a wavelength λ = 10600 nm in CW and pulse regime. The examined parameters were: the mean power, the regime (CW or pulse), the beam speed, and the number of laser scansions, also called repetitions. The working parameters and the engraved depth were related. From the results, an empirical model was derived, by which the engraved depth was predicted as a function of the process parameters
