Effects of the Inclination Angle of the Knife Upon the Roughness of the Workpiece Cutting-Surface and the Deformation of the Chip in the Transverse-Plane (90°-90°) Cutting of Wood

摘要

This report clarifies the effects of the inclination angle (i) of the knife upon the roughness of the workpiece cutting-surface and the deformation of the chip in the 90°-90°cutting (edge perpendicular, moving perpendicular to the grain direction) of wood. Air-dried specimens of different wood species having a wide range of specific gravity (ru) were used in this study, and were cut by feeding a knife, which was set on the experimental apparatus (Fig.2). The deformation of the chip and the roughness of the workpiece cutting-surface were observed relatively and estimated sensuously. The results of them were shown (Table 1 and Figs.3-5), and the effects of i and the workpiece conditions (ru, the wood species and the orientation of the annual rings to the cutting direction on the workpiece cutting-surface) upon them are discussed.
