Experimental Laser Cutting Material Removal Rate for Polymethylmethacrylate in Construction Applications

Abstrak

This research aims to optimize the laser cutting process on polymethylmethacrylate (PMMA) to improve efficiency and quality in construction applications. By exploring the influence of variations in laser current, cutting speed, and material thickness, this study sought to identify the optimal parameters that resulted in the highest material removal rate (MRR) with minimal overcut. Through a series of experiments testing various parameter combinations, the study found that a cutting speed of 40 mm/s, laser current of 80 A, and material thickness of 3 mm yielded the best cutting performance. The results show that optimization of laser cutting parameters can significantly improve the precision, energy efficiency, and quality of PMMA cutting results. The implications of these findings are significant for the development of more efficient and sustainable laser cutting techniques, supporting the use of PMMA in various innovative construction applications such as facades, decorative elements, and architectural prototypes. This research contributes to the understanding of PMMA laser cutting process optimization, with the potential to expand the application of this material in the construction industry through more efficient and quality fabrication methods.
