Paper presents analysis of the process of removing the wood chips generated during the cutting of the material on the circular sawing machine. The attention is focused on the upper cover of the chip removing system. Within the framework of the work a systematic experimental study of pressure distribution in the cover during operation of the selected rotational speed of saw blade with a diameter of 300 mm and 450 mm was carried out. Analysis of the results allowed to predict the areas with insufficient vacuum pressure hindering the organized transport of chips. In addition the effect of a 20% change in the fan speed on the pressure range in these areas has been investigated. The obtained results will be used by the authors in the process of optimizing the shape of the cover to improve the process of chip extraction. It will also be helpful in interpreting the results of numerical analyzes conducted in parallel.
