• Tactile roughness of planed wood was investigated in relation to geometrical surface roughness and growth ring structure of the wood. Specimens used were small quarter-swan plates of eleven species shown in Table I. In order to evaluate tactile roughness of the specimens, sensory tests by human hand were executed by the method of paired comparison, and the data were analyzed by the composite standard technique. Other roughness values of the specimens were measured with the instrument of the stylus method. Furthermore, the growth ring structure of the specimens was observed with naked eyes and a magnifier, and photographed with a camera. The tactile roughness expressed as the psychological value Z did not show a significant correlation with the center line mean roughness of the specimens, but with the roughness of real profile curve R_m defined as in Fig. 1(a). The R_m had also a highly significant correlation with the waviness of real profile curve W defined as in Fig. 1(b), which in most cases indicated good correspondence to the waviness of the growth ring structure. Thus the tactile roughness of the planed wood seems to come largely from the waviness such as the growth ring structure , rather than the porous structure of cellular elements in the wood.
