  • Frequency analyses of voltage signal IR radiation from the cutting front and cut surface at laser cutting of austenitic stainless steel
    Grum, Janez, 1946- ; Zuljan, Darjo
    Efficient control of laser cutting processes is closely related to knowledge of heat effects in the cutting front and its surroundings. Similarly to other machining processes using high power ... densities, in laser cutting processes it is very important to monitor the heating phenomena in the specimen material due to heat input. The processes in the laser cutting front were monitored in three ways, i.e., by a voltage signal of IR radiation from the cutting front during cutting, by measuring surface profiles of laser cuts, and by macrographs of laser cut surfaces. In the paper it is proved that an analysis of macrographs showing surface-profile corrugation of the laser cut in austenitic stainless can be used to confirm and analyse thermal phenomena in the cutting front. The paper gives a comparison between amplitude spectra of the voltage signal of the infrared (IR) radiation and amplitude spectra of the surface-corrugation profile for different specimen thicknesses, and various input energies.
