A possibility was investigated to calculate the surface roughness of woods by band sawing by using the acoustic emission count rate, the cutting force and the specific gravity of woods. Five different softwoods, four different ring-porous woods and eight different radial- and diffuse-porous woods were used as workpieces. Ripsawing was carried out. The acoustic emission count rate was measured by the ring down method using a measuring system with a microphone. The cutting force in the cutting direction was measured using a load cell attached to the feed table. The surface roughness of a wood measured by a contact instrument with a stylus of 0.25mm curvature was described by ten point height of irregularities. The results obtained in this study are summarized as follows: The surface roughness of softwoods and ring-porous woods can be calculated by the multiple regression of the specific gravity of woods, and the AE count-rate or the cutting force. The multiple regression using the AE count-rate is more precise than using cutting force for the calculation of softwoods and ring-porous woods. The surface roughness of radial- and diffuse-porous woods can be calculated by the linear regression of the AE count-rate when they are classed by the similar characteristics of their structures. Moreover, it can be calculated by the multiple regression of the specific gravity of woods and the cutting force.
