Table 6 The comparison of the values derived from the results of the experiment and the carried out multi-linear regression analysis
From: Determination of machinery and knife strains in the planing of wood-based panels
Wood-based panels | Engine revolution speed (rev/min) | Drive forward speed (m/min) | Real current values (A) | Predicted current values according to the regression model equations (A) | Differences, between predicted and real current values (%) | Arithmetic mean (%) | Wood-based panels | Engine revolution speed (rev/min) | Drive forward speed (m/min) | Real current values (A) | Predicted current values according to the regression model equations (A) | Differences, between predicted and real CURRENT values (%) | Arithmetic mean (%) |
