Studies on Machinability of Bamboo Culm. V : Effects of Various Cutting Conditions on Variations of Cutting Phenomena at Various Stem-Wall Tangential Sections in Orthogonal Cutting of Bamboo 2 : Effects of clearance angle in 0^。- 90^。 cutting

摘要

The purpose of this study is to make clear the machinability of the bamboo culm. Using Mosochiku (Phyllostachys pubescence MAZEL) grown at Kyushu district, the variations of the cutting-force components in orthogonal cutting of the bamboo culm were measured (Figs. 1～12 and Tables 1～2), the effects of internode region and nodal region in the stem wall, the bamboo culm in the radial direction and the longitudinal direction, and clearance angle of the knife upon the variations of the cutting-force components and the other cutting phenomena were clarified (Figs. 13-17). Based on these results, characteristics of the orthogonal cutting of bamboo in this study are discussed.
