Thermal modelling of cutting front edge dynamic behaviour in high-power reactive CO2 laser cutting

摘要: AbstractThe sheer number of non-linear interacting factors responsible for the performance laser cutting makes it impractical, in general, to investigate all by experimental method only. To understand further essential phenomena oxidation reaction reactive CO2 cutting, a mathematical model was created this research effects parameters on front edge dynamic behaviour. Understanding various is important improving and quality cutting. The thin metallic plate utilizing continuous-wave beam having Gaussian intensity distribution considered study. Both absorptivity heat generated at during process were research. numerical results work can be used predict or estimate variations location, speed acceleration cuttin...
