Abstract: This report clarifies the effects of the Inclination angle of the tool (I) and the grain angle of the workpiece (φ_1) upon the components, the resultants of the cutting force, and the frictional coefficient in the oblique cutting of wood parallel to the grain. Air - dried specimens of sugi (Cryptomeria japonica D. Don ), hinoki (Chamaecyparis obtusa), and American western hemlock (Tsuga heterophylla Sarg.) were used in this study. They were cut by the feeding of a tool which were set on the experimental apparatus equipped with a three - dimensional elastic - ring dynamometer (Figs. 1~4 ). The lateral (F_X), main (F_Y), and thrust (F_Z) components of the cutting force acting on the tool were measured. In addition to the measurements of these three components, several cutting phenomena were observed and measured. Using the measured components given above, the resultant forces (R and R_C) and the frictional coefficient on the tool rake - face (μ) were calculated, and the effects of the cutting conditions (I, φ_1, and depth of cut (t_n)) and the effects of the wood species upon them are discussed.
