Contrast Prediction for Laser Direct Part Marked Data Matrix Symbols on Titanium Alloy Substrates

Abstract:

To establish a mathematical relationship between Nd:YAG laser parameters and the qualities of laser direct marked Data Matrix symbols on titanium alloys, multiple linear regression analyses were performed based on orthogonal experiment results. According to the analysis results, the paper developed a prediction model to estimate the contrasts of laser direct marked Data Matrix symbols (i.e. Symbol Contrast). The prediction model was statistically analyzed by regression analysis and multi-factor analysis of variance (ANOVA). The predicted symbol contrasts were compared with the experimental values and they were close. The multiple linear regression analyses results showed that the developed prediction model was extremely significant and could be used to estimate the symbol contrast in laser direct part marking.
