Abstract:The relationship between wood density and cutting resistance of 15 Chinese hardwoods was studied following the corresponding studies on 11 coniferous woods. The main discovery made during the latter and further confirmed herein is that the change of the relation between wood density and cutting resistance affected by chip thickness,knife rake angle, and wood moisture content exhibited a common tendency, no matter which one of the three factors changes.the higher the resultant level of cutting resistance,the larger the regression coefficient and the remained standard deviation of the densitycutting resistance correlation. The regression equations describing this tendency for hardwoods are presented. Furtheremore, the factors affecting the scatter of the density-cutting resistance relation were investigated and discussed.A more detailed general report in English is available from the author.
