Influence of wood modification on cutting force, specific cutting resistance and fracture parameters during the sawing process using circular sawing machine
Original language description
The aim of this study was to determine the cutting force and specific cutting resistance of modified beech wood (Bendywood, DMDHEU and Lignamon) and, based on experimental results, to calculate the fracture parameters for cutting in axial-perpendicular direction of these modified materials and to compare with native beech wood. In the conventional approaches, cutting force and cutting power in sawing processes of wood are generally calculated based on the specific cutting resistance, which is a function of many factors. A major deficit of these conventional methods is that they are not focusing on the physical and mechanical properties of wood. The influence of these factors is only taken into account by the coefficient of the tree species. In this work, predictions of the newly developed model for the circular sawing machine are presented. Thanks to this modern approach, it was possible to determine fracture toughness and shear yield strength of native beech wood and modified beech wood using experimental results, without performing complex fracture tests. Based on the experiments performed, it can be concluded that modifications have a partial degradation effect on wood properties. The fracture toughness and shear yield strength of the modified materials is not dependent on the density, but rather on the internal structure, extent of the degradation of the cell wall and the type of modification.
