Abstract
This paper examines the processing roughness of beech surfaces sanded with 13 grit sizes from P60 to P600 after the separation from wood anatomy and quantifies the biasing effect of wood anatomy when it is not removed. When the anatomy was removed there was a strongly correlated logarithmic variation of the roughness parameters with the grit size. When the anatomy was not excluded, the bias was small for grit sizes from P60 to P100, gradually increased from P120 to P280 and increased sharply from P320 onwards. Processing roughness, even for a diffuse porous species such as beech, should be separated from anatomical irregularities if the effect of grit size is to be properly evaluated.
