Abstract

In order to study the effect of laser cutting process parameters on the slit width of garbage bags made of polyethylene (PE) material, Box-Behnken test was designed to test the cutting of polyethylene film using a 30 W fiber laser marking machine. Measurement of the slit width of polyethylene films using a Nikon microscope was used to analyze the pattern of the effect of different process parameters of the laser marking machine (amount of defocus, cutting speed, and laser power) on the slit width. Process parameters are optimized based on regression equations and actual cutting results. Based on the analysis of the experimental data and the modeling results, it can be determined that the effect of laser power and cutting speed on the slit width of polyethylene film is significant and strong, while the effect of the amount of laser defocus is relatively weak and of secondary importance. Finally, a validation test was conducted to obtain an average error of 6.167% in the model predictions.
