  • Optimisation of the process of laser cutting steel
    Grum, Janez, 1946- ; Zuljan, Darjo
    Efficient control of laser cutting processes is closely related to the knowledge of heat effects in the cutting front and its surroundings. Heating effects in the cutting zone influence cut quality. ... Similarly to other machining processes using high power densities, in laser cutting processes it is very important to monitor the heating phenomena in the workpiece material due to heat input. In laser cutting processes with oxygen as an auxiliary gas, cutting energy is a combination of laser beam energy and the energy of the exothermic reactions occuring in the cutting front. The presence of oxygen in the process increases cutting efficiency, but it also causes additional physical processes in the cutting front which render a more detailed analysis of the cutting phenomena difficult. The aim of the article is to analyse the emission of infrared rays from the cutting front with a photo diode, statistically analyse the signals infrared radiation and optimise the laser cutting process based on a critical cutting speed.
