ABSTRACT The theory and practice of laser applications in material processing highlight the role of the laser spot defined as a cutting tool for efficiency. The main objective of the research is to calculate the spot correction radius, energy density, power density, specific energy resulting from the emission of laser light by CO2 and Fiber installations with wavelengths of 10.6 µm and 1.06 µm. The Kerf cutting width measured on Hardox400 steel, thickness g=10 mm, output variable, in power laser processing processes is an important technological parameter that validates the correction radius and specific energy. The spot diameter is a working parameter that enters the estimation of mathematical relationships that was established manually, CO2 laser (0.30 mm) and automatically set with sensors, Fiber laser (0.38 mm). The results obtained were compared and discussed to comment on the correction radius, so that the mathematical model (r_correction=0,21 mm) reconfirms the experimental model (r_correction =0.25mm), it results that the two analyzed models confirm each other. The specific energy ∈_s=2080,25 J/mm2 obtained by the CO2 laser and the specific ∈_s=1892,4 J/mm2 obtained by the Fiber laser, justify at this point that for thick sheets the carbon dioxide laser ensures quality when cutting the samples. |
