  • The huge difference within the annual rings of Douglas fir between the latewood and early wood density affects quality of the surfaces resulting from the machining process. Nevertheless the quality of machined surfaces may be improved through a suitable machining process. To achive this goal is necessary to describe the types, the quantities and the areas affected by the different defects. Douglas fir specimens coming from European plantations were processed according to various grain angle; the specimens were: 1)visually graded according the ASTM 1666, into grades and different types of defects of the standard(raised grain, fuzzy and torn grain); 2) analysed by a contact laser 3D roughness device, in order to obtain the numerical description of the whole area considered. The diffent methods have been then compared and discussed. (literal)
