Summary: This article presents the results of research related to selecting the optimal (recommended) process parameters for engraving with a low-power semiconductor laser. Engraving on experimental wood samples of pine, spruce, birch, beech, maple, and plywood was performed using the same laser settings. The results showed that increasing the number of passes increased the depth and width of the engraving for all materials. The greatest engraving depths were observed for spruce (0.8 to 2 mm), and the smallest for beech (0.35—0.9 mm). This demonstrated that the wood species significantly influenced the engraving result. Research results have shown that birch was one of the optimal woods for laser engraving, due to its combination of physical, chemical, and anatomical properties, ensuring good engraving “legibility”. Plywood was also well suited for engraving (good workability, clean cut). Laboratory measurements of the engraving depth and width using experimental and computational methods, as well as visual testing of the quality of engraved images on test samples at different power, speed, and pitch values, allowed us to identify the recommended engraving process parameters for wood and wood-based materials using a low-power semiconductor laser. The results presented in this article can form the basis for further research into the substantiation and selection of optimal laser engraving modes and parameters.
