Study on the Influence of Certain Factors on the Sound Pressure Level Generated During Cutting with the Circular Saw
Abstract
In the current study, the changes in the sound pressure level (SPL) measured at the workplace and generated by the woodworking sliding table circular saw machine F45 (Altendorf, Germany) were investigated. The influence of the processed wood, in this case, specimens from Pinus Sylvestris L. and Fagus Silvatica L., as well as the thickness of the processed material and the rotation frequency of the circular saw on the total level of the generated noise, were evaluated. The influence of the tool overhang effect on the changes of the sound emissions was also measured. The changes in the SPL were measured in octave frequency bands with average frequencies ranging from 63Hz to 16kHz. During the experiments, the characteristics of the sound field were also taken into account. On the basis of the obtained results, graphical relationships between the investigated parameters and the changes in the SPL were derived. The experiments were carried out in compliance with the BDS EN ISO 3744 and BDS ISO 7960
