Abstract


The log models are created based on the results of log sawing into lumber in working conditions. The simulation of sawing for each log into lumber by through-and- through method with consideration of log rotation concerning its longitudinal axis was performed. It is determined that the angle of log rotation concerning its longitudinal axis can considerably influence lumber volume yield. The difference of limit values in the range of change for lumber volume yield of investigated variants was 1.52-23.58 %.
