Abstract: In the wood cutting process, it is important to obtain the actual stress distribution on the rake face during cutting and to investigate the changes in stress distribition and frictional coefficient with workpiece condition. In order to obtain quantitative information on them, the basic orthogonal cutting tests were performed using the same conventional and composite tools as used in the previous reports. The results obtained are summarized as follows : (1) The distributions of the frictional stress (τ) and the normal stress (σ) on the rake face can be expressed by Eq. (3) (2) On the basis of the experimental results (Eq. (1), and Figs. 2 and 3 ), the ratio of the cutting force on the tool face near the edge to the total cutting force on the tool face can be calculated from Eq. (4), and the values are shown in Table 2 . (3) The frictional coefficients (μ_2) on the rake face can be expressed by Eq.(5). On the rake face, μ_2 can be considered to be constant, and the values of μ_2 are shown in comparison with the other frictional coefficients, in Table 3.
