Abstract


In the present work, the simulation of multi-pass laser cutting on PMMA has been investigated in Abaqus by considering script for variation in Gaussian distribution of energy. Ablation depths were predicted at each pass during laser cutting at Power 30 W and 55 W with cutting velocity at 20 mm/sec. It was observed that Ablation depth increases with the increase in power and number of passes at a constant speed. The simulation results have been compared with the experimental results. It was found that the deviation occurred in the range of 10% to 32% due to energy applied in actual cutting and assumption applied in script for specific energy concept towards deletion of element for visualizing cutting depth.
