Abstract


Laser engraving is an advanced technique for precise application of markings on the surface of molds, offering advantages such as high accuracy, wear resistance, execution speed and the ability to mark complex surfaces. This environmentally friendly method ensures good long-term readability without the use of chemicals. The study presents multi-objective optimization of engraving parameters, using experimental design and gray relational analysis to simultaneously improve surface roughness, engraving depth and processing time. By analyzing seven input parameters, the research identified the optimal settings and the factors with the greatest influence on the process, demonstrating the effectiveness of the method and opening new perspectives for improving the process performance.
