MATHEMATICAL MODELLING OF THE PROCESS OF DECORATION OF FELT SHOES BY SURFACE PYROGRAPHY

The article considers the issue of the effect of laser pyrography on felt samples for the purpose of decorating the upper of shoes. The results of mathematical modelling of the process of laser decoration of upper parts of felt shoes are presented. Particular attention is paid to the assessment of the coefficients of the regression model for finding which, the least squares method was used. The characteristic features of checking the significance of coefficient estimates, performed according to the standard method of linear multivariate regression analysis, are described. The adequacy of the model was checked by the square of the determination coefficient. The conducted research and calculations proved that contour burning should be used in felt shoes, since a complex pattern will be used for its decoration, which is created using special software.
