INVESTIGATION OF NOISE AND VIBRATION OF CUTTING CIRCULAR SAWS
Description
The article presents the results of theoretical studies of noise cutting circular sawing machines. Practical calculation of the noise spectra is based on the determination of the dependency of the sound pressure of the noise sources of the object of study. In the sound system, circular sawing machines sound energy is emitted by the following sources: disc cutter and the mandrel. Therefore, the dominant noise sources should be allocated to the technological subsystem "tool – mandrel” with a bit less rigidity than the carrier system of the machine and directly receives the cutting forces when milling. Thus, it is possible to reduce sound pressure levels in almost two ways: by increasing absorption production facilities and (or) decrease in sound pressure of the noise source. In this work, we have justified the second way – reduction of the intensity of acoustic radiation of the source

EXPERIMENTAL STUDY OF NOISE AND VIBRATION OF THE BAND SAW FRAME SAWS AND WOODWORKING MACHINES
Description
The article presents the results of experimental studies of band noise generation and multirip woodworking machines. The studies have shown that saw woodworking group, as well as metal, are general patterns in the formation of the spectral composition that allows to approach the development of practical recommendations to reduce sound pressure levels in the work area to the operators of sanitary norms. Of particular note is the fact that elevated levels of noise generated by the cutting tool. The effect of changes in process parameters, in particular, the depth of cut and feed to levels of noise generated by the tool. For example, increasing the depth of cut in half leads to an increase of sound pressure levels at 5.8 dB (theoretically obtained value is 6 dB), and supplying a halving of the sound pressure levels reduces by 5 dB. High enough for engineering purposes convergence of theoretical and experimental sound pressure levels and the fact that the calculated values above experimental, allows the calculation and design of the system to reduce the noise under consideration in the machine is, only in service but also in their design
