Problems solved by technology

[0004] At present, in the field of laser marking, the orthogonal experiment method is usually used to optimize the parameter combination. However, in the early stage of the orthogonal experiment, the factor level is usually determined based on manual experience and the orthogonal factor level table is formulated. There is a lack of objective and scientific methods. Make the determined factor level and the formulated orthogonal factor level table inaccurate, resulting in low accuracy of the finally sought parameter combination, thereby affecting the pattern quality
