Sawing processes in sawmills are characterized by high consumption of electric energy. As cutting tools with geometrically defined cutting edges, circular buzz saw blades have a direct influence on cutting performance and thereby on the electric energy consumption of the cutting process. Thus, energy efficiency is directly linked to cutting forces, which are determined by the geometry of the saw-tooth and the material properties. In this paper, the energy consumption within cutting frozen wood at sub-zero temperatures is analysed. Results are presented and will lead the development of geometries for saw teeth to increase the sustainability of cutting frozen wood.
