Research on plastic working of wood is done with the aim of the effective use of the resources and the improvement of function of wood. There have not been so many studies on the deformation behavior in plastic working of hardwood. For actual processing of hardwood, frictional behavior of wood was investigated. Coefficients of friction were measured for maple, oak and walnut. The change of the contact pressure and slide speed did not give the change to the coefficient of friction. Although coefficients of friction were 0.5∿0.6 for tool with 9μm surface roughness, they decreased to 0.1∿0.4 for tool with 0.4μm surface roughness. It is considered that the tool surface adheres to the specimen when the tool surface is rough, and that lubrication film is formed by the water which consists inside the specimen when the die surface is smooth.
