Fracture mechanics model of cutting power versus widespread regression equations while wood sawing with circular saw blades
Abstract
A comparison of the theoretical cutting power consumption results forecasted with the model (FM_CM model) which include work of separation (fracture toughness) in addition to plasticity and friction, and two widespread regression equations while wood sawing with circular saw blades has been described. in and cutting power consumption forecasted. In computations of the cutting power consumption during rip sawing of Scots pine wood (Pinus sylvestris L.) of the Baltic Natural Forest Region (PL) provenance values of fracture toughness and shear yield stresses were taken from previous empirical works. The carried out analyses revealed a lack of conformity of the results obtained with regression equations if compared with the FM_CM model.
