Rezumat:
         In cele mai multe cazuri, taierea lemnului cu panze circulare se realizeaza la viteze de avans si viteze de taiere mari. Panzele circularului se rotesc si in exteriorul masinii, fiind astfel o sursa de zgomot cu efecte nelipsite in mediul de lucru. In aceasta lucrare se prezinta rezultatele masurarii nivelului de zgomot pentru trei tipuri de panze circulare, structural diferite. Cele trei tipuri de panze circulare sunt urmatoarele: cu sase fante de compensare in directie radiala, cu sase fante de compensare in directie tangentiala si cu sase fante de comensare in forma de S. Diametrele panzelor circulare sunt de 350 mm. Masuratorile asupra nivelului de zgomot s-au realizat in timpul procesului de taiere utilizand echipamentul standard. Panzele circular cu fante de compensare au emis zgomot la un nivel inalt, dar diferit. Panza circulara cu fante de compensare in forma de S a avut nivelul de zgomot cel mai redus in comparatie cu celelalte tipuri, situandu-se in intervalul (2 5) dB (A).

Cuvinte cheie: panza circulara, fante de compensare, frecventa naturala, nivel de zgomot la taiere.
