  • Technological parameters optimization by GA and influence on the quality of laser cutting
    Čuš, Franc, 1953- ; Milfelner, Matjaž ; Balič, Jože
    The paper discusses the use of the laser system in production and the influence of laser cutting parameters on the quality of manufacture. In order to reach high accuracies of laser cutting it is ... necessary to introduce new machining technologies, to automate the cutting process and to adapt the cutting process to different sizes and shapes of workpieces and to other requirements in machining. In the final stage the quality of the cutting is analyzed and the laser cutting parameters are optimized. Therefore it is very important to describe adequately the cut with various quality characteristics (cut shape, waviness and/or roughness of the cut surface and presence of burr on the workpiece lower edge). The paper describes the influence of various technological parameters on the quality of laser cutting for the C02 laser system. Initially, the cutting parameters (cutting speed, output power of laser beam, frequency, working mode, gas pressure, etc.) are important for the programmer of the laser system and in the second stage for the machine operator. Presentation of applicability is based on a practical example of optimization from production by genetic algorithm. The benefits of use of laser systems are savings of material, possibility of machining different materials of different thickness, high quality and productivity and the fact that the tool change is not necessary and reduction of production costs.
