抄録: The orthogonal cutting tests of veneer, by feeding a knife to the workiece during the sliding of the knife in the direction parallel to the cutting edge, were performed (Fig, 2). Air-dried specimens of white seraya (Parashorea malaaanonan Merr.), which were fixed to the experimental apparatus equipped with a three-dimensinonal elasticring dynamometer, were cut during the feeding of the knife (Table 1, and Fugs, 3~8). The components and the resultant of the cutting force were measured. Using these results, the effects of the ratio (f) of the sliding velocity (Vk) to the feeding velocity (Vw) and the grain angle (φ) of the workpiece, upon variation of the cutting force and the other veneer-cutting phenomena were clarified (Figs.9~23, and Tables 2~4). Characteristics of the veneer-cutting method used in this study are discusssed, comparing it with the conventional orthogonal cutting of veneer. The main tendencies of the variations of the components (Fx, FY, and Fz) of the cutting force acting on the axes of X, Y, and Z, as shown in Fig. 2, and the resultant (R) of their components were: (1) The value of Fx increases, the value of Fy decreases, and the value of Fz increases or is constant, with increases in f (Figs. 9 and 10); and (2) Although R and their components have a minimum value at φ=0°and increase with increases in the degree of φ, their increasing tendencies depend not only on the sliding direction of the knife but also on the degree of φ(Figs. 11 and12).
