【 摘 要 】

The sound levels along with the cutting power registered during the sawing process of the impregnated and non-impregnated pine wood at two feed speeds are shown and compared in this paper. Statistically significant differences in the acoustic signals occurred at the lower feed rate. The differences became smaller with an increase in the feed speed. In contrast to the sound signal, the differences in the cutting power were statistically significant only for the higher feed rate. In addition, the average electric power of the main drive allowed for the identification of knots during the sawing process. Obtained results indicated that monitoring based on the analysis of sound signals can be used as a supplementary source of information related to the wood cutting processes. This kind of independently used monitoring could be recommended for long-running and stabilized sawing processes, due to high noise level generated during the transition states when the tool enters and exits the material transition states.
