Treść
A comparison of experimental results obtained in the industrial conditions at a sawmill located in the Baltic Natural Forest Region (PL) and theoretical cutting power consumption forecasted with the models which include work of separation (fracture toughness) in addition to plasticity and friction has been described. In computations of cutting power consumption during rip sawing of Scots pine wood (Pinus sylvestris L.) values of fracture toughness and shear yield stresses were taken from previous empirical works, in which samples had been of the same provenance. The carried out analyses revealed conformity of experimental and theoretical results, especially for the model FM-CM, for which differences between them were lower than 3%.
