抄録: Orthogonal cutting tests of veneer, by feeding a knife to the workpiece during the sliding of the knife in the direction parallel to the cutting edge, were made. Air-dried specimens of white seraya, which were fixed to the experimental apparatus equipped with a three-dimensional elastic-ring dynamometer, were cut during the feeding of the knife. The components and the resultant of the cutting force were measured. Using these results, the effects of the ratio (f) of the sliding velocity (V_k) to the feeding velocity (V_w) and the grain angle (φ) of the workpiece, upon the cutting force were clarified. Characteristics of the veneer-cutting method used in this study are discussed, comparing it with the conventional orthogonal cutting of veneer. The main tendencies of the variations of the components (F_X, F_Y, and F_Z) of the cutting force acting on the axes of X, Y, and Z, and the resultant (R) of their components were : (1) The value of F_X increases, the value of F_Y decreases, and the value of F_Z increases or is constant, with increases in f 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.
