Dynamics of cutting power during sawing with circular saw blades as an effect of wood properties changes in the cross section

Abstract

In the paper the effect of the method calculation upon the cutting power is presented. In computations were used models in which fracture toughness was incorporated. The comparison concerned models as follows: FM-CM – classic model in which the sum of all uncut chip thicknesses of the simultaneously teeth engaged represented the mean uncut chip thickness, FM-FDM – full dynamical model in which besides variable uncut chip thickness additionally variable values of fracture toughness and shear yield stresses according to the tooth position in relation to the grains were taken into account, and FM-SDM – semi dynamical model in which in which uncut chip thickness is variable, but fracture toughness and shear yield stresses are constant and equal to the mean values. The largest values of the cutting power have been obtained while the FM-SDM model applied.
