Abstract:

This paper investigates the possibility of measuring the surface roughness of wood by the laser displacement sensor. Ten points_based mean roughness of the planed surface of Douglas, Hinoki, Beech and Padauk was measured by using the laser displacement meter and the stylus instrument to clarify the characteristics of both instrument. The measured roughness from the laser displacement sensor at the processing speed of 6 m·min^-1 for forth wood specimens coincided with the value obtained from the stylus instrument by using a proportion coefficient between them.

Key words: laser displacement sensor, quantitative measurement, wood, surface roughness
