The main purpose of this report is to make clear the effects of the grain angle (φ) and the inclination angle (i_w) of the workpiece upon the chip deformation in the orthogonal wood cutting by feeding the workpiece inclined to the feeding direction. Air-dried specimens of red meranti (Shorea sp.) were used for this study. The cutting tests of these specimens were performed, using a modified cutting-machine. The sizes of the chip, the chip deformations, the chip flow angles (η_c), and the several cutting phenomena were observed and measured. Based on these results, the effects of the workpiece conditions (φ and i_w) upon the chip deformations were discussed, and the chip deformations were classified into the several types, under various combinations of φ and i_w.
