This report clarifies the effects of the inclination angle of the workpiece (I) and the depth of cut (t_n) upon the cutting - force components and the frictional coefficient in veneer cutting. Air - dried and water - saturated specimens of tangile (Shorea polysperma Merr.) were used in this study. The veneers were cut by feeding the specimens, which were set on the experimental apparatus equipped with a three - dimensional elastic - ring dynamometer, to the cutting edge of a tool (Fig. 1). The longitudinal (F_Y), thrust (F_Z), and lateral (F_X) components of the cutting force acting on the workpiece were measured. In addition to the measurements of these components, several cutting phenomena were observed and measured. Using the measured components mentioned above, the normal (N), frictional (F), and resultant (R) forces and the frictional coefficient (μ_<min>) of the tool were calculated, and the effects of the cutting conditions (I and t_n) and the effects of the workpiece conditions upon them are discussed.
