SUMMARY:

This study investigated the influence of process parameters in drilling of ABNT 1020 steel sheets using laser cutting process. The research focused in parameters variation of laser cutting machine power, cutting speed, and nozzle height and the influence of these parameters on the cutting quality. Using the design of experiments technique, a series of cuts were performed on ABNT 1020 steel sheets with varying input parameters configurations to analise the impact on characteristics such as hole precision, surface roughness, and cut quality. Results showed that laser power and cutting speed had a direct relationship with both surface roughness and roundness. On the other hand, the nozzle height influenced more the circularity errors. Data analysis allowed the identification of optimal conditions to maximize cut quality. This study provided valuable guidelines for optimizing laser drilling processes in industrial applications, with practical aplications in improving product quality.
