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.
