Research on Process Optimization of 3D Laser Cutting Robot for Three Dimensional Aluminum Components

In order to solve the precision problem of laser cutting of 3D aluminum components, the influence of main process parameters on the characteristics of laser cutting was studied. Firstly, the model of 3D laser cutting of complex curved surface was studied, and the heat transfer mechanism of 3D laser cutting of aluminum materials was revealed. Through the three-dimensional laser cutting robot test bed, aluminum material is taken as the test object, the reasonable laser cutting parameters are selected, and the influence law of each process parameter on the cutting quality and the morphology of the slit is studied. Experimental studies shows that low surface roughness was achieved with some combinations of process parameters and attempts were made to optimize parameters in terms of cutting speed and laser power. It is obtained low surface roughness, with power 800w, cutting speed 40mm/s for 1mm aluminum.
