The cutting tests were carried out using the samples of Scotch pine (Pinus sylvestris L.) from Pomeranian Region, Poland. These experiments were carried out on two research stands: orthogonal linear cutting tests were conducted using the microtome instrument and the frame saw PRW-15M was used for sawing tests. The values of the fracture toughness were determined following the recorded values of cutting power during the cutting tests (PRW-15M) and cutting forces (microtome instrument) with the use of models based on the elements of fracture mechanics. It was observed that the fracture toughness values determined following the orthogonal linear cutting tests were significantly lower, what could be caused by bending the wood fibers under the pressure of the cutting force.
