Influence of feed speed on emission of fine sawdust during circular sawing

This paper presents granulometric analysis of sawdust generated in processing oak-wood, fir-wood and particleboard with circular saw at three different feed speeds and two working table position. Woodworking machines and cutting parameters, as well as processed material properties determine the particle size distribution of chipped wood and as a result also the emission of airborne wood particles at the workplace. The objective of this paper was to clarify the influence of feed speed, cutting angle and wood material characteristics on particle size distribution of sawdust generated during sawing of solid fir-wood (Abies Alba Mill.), oak-wood (Quercus Robur L.) and laminated particleboard with circular saw. Generally, the results showed that the share of small particles in sawdust decreases with the increase of feed speed. Working table position and cutting angle have very important influence on particle size distribution of sawdust when cutting solid wood.
