Vitchev, Pavlin Influence of the processed material on the sound pressure level generated by sliding table circular saw / Pavlin Vitchev, Dimitar Angelski, Vladimir Mihailov. -- Obr., tab. -- The aim of the current study isto investigate the changes in the sound pressure level generated at the operator’s position of sliding table circular saw depending on the type of the processed material, the cutting height (h) and the tool overhang effect (T) (T1= 7; T2= 14;T3= 21 mm). The experiments were performed with specimens from chipboard oriented strand board (OSB) and plywood with cutting height of 15, 30, 45 mm. The generated sound pressure level was measured using the method of “sound free field” taking into account the influence of the background noise and the characteristics of the sound field. The measurement of the A-weighted sound pressure level was performed using precise digital sound level meter CEL-620B1 (CASELLA, United Kingdom). The obtained results showed that the sound pressure level is influenced by the type of the processed material and it is changed at the cutting height of 15 mm as follows: plywood–89.5 dB(A); OSB –88 dB(A) and chipboard–86.5 dB(A). An increase in the tool overhang effect from 7 mm to14 mm resulted in an increase in the sound pressure level by 3÷4 dB(A) on average for all three types of processed material.
