Paper presents the analysis of the results of numerical simulations of the air flow process of wood chips removing system in the circular sawing machine. The attention is focused on the upper cover and bottom shelter of the chip removing system. Within the framework of the work a systematic numerical modeling of the air flow distribution in the cover and shelter during operation of the selected rotational speed of saw blade with a diameter of 300 mm and 450 mm was carried out. The analysis of the results obtained from the numerical simulations and from the experimental measurements allowed to predict the areas with improper air movement hindering the organized transport of chips. Also, those results from the numerical modeling were used in the process of optimizing the shape of the casing and the shelter. As a result, a new design of chip removing system was obtained, vastly improving the chips extraction from the tool operation space.
