| Abstract | ||
| This research is devoted to study the effect of a laser beam power TEA-CO2 , Nd- YAG laser, and thermal properties of the materials when it is constant once and varying another once with the time on the penetration and cutting speeds. It is concluded that the processes of penetration and cutting by using laser Nd-YAG is the best comparative with using of laser TEA-CO2, penetration speeds when (P = P0, C = C0, and ρ = ρ0) by using laser Nd-YAG greater than penetration speeds by using of laser TEA-CO2 by 15.5 approximately while penetration speeds when (P = P(t), C = C0, and ρ = ρ0) by using laser Nd-YAG greater than penetration speeds by using of laser TEA-CO2 by 8.519 approximately. In addition, the temperature of the evaporation of material plays an important role in the processes of penetration and cutting and whenever temperature of the evaporation of material less the cutting and penetration speeds are greater. (MATLAB 8) program was implemented for all simulation processes are related. | ||
