STRESZCZENIE: W artykule przedstawiono prognozowane wartości mocy skrawania dla pilarki taśmowej (ST100R firmy STENNER), które są stosowane w polskich tartakach. Wartości mocy skrawania oszacowano dla drewna sosny zwyczajnej (Pinus sylvestris L.), które zostało poddane impregnacji. Dla porównania wyznaczono również wartości mocy skrawania dla drewna niezaimpregnowanego. Wartości te określono za pomocą innowacyjnej metody prognozowania sił skrawania, która uwzględnia elementy mechaniki pękania. Uzyskane w ten sposób prognozy porównywano z wartościami mocy skrawania otrzymanymi metodą klasyczną, opartą na właściwym oporze skrawania.

SŁOWA KLUCZOWE: moc skrawania, drewno sosnowe, drewno impregnowane, pilarka taśmowa

ABSTRACT: In this paper the predicted values of cutting power for band sawing machine (ST100R), which is used in the Polish sawmills, were presented. The values of cutting power were determined for wood of Scots pine (Pinus sylvestris L.), which was impregnated and not impregnated. These values were estimated using an innovative method of forecasting cutting forces, which takes into account the elements of fracture mechanics. The forecasts obtained in this way are compared with the values of cutting power estimated with the use of the classical method, which is based on the specific cutting resistance.
