Abstract: In the cutting of bamboo culms, it is important to clarify variations of the cutting-force components acting on the knife and the frictional coefficient on the rake face of the knife, but few studies have dealt with the effects of various cutting conditions and various workpiece conditions on them. Therefore, the main purpose of this report is to supply quantitative information on these aspects. Orthogonal, linear cutting tests of bamboo culms with 0°-90°and 90°-0°cutting directions were made (Figs. 1 and 3). Air-dried specimens of mosochiku (Phyllostachys pubescens MAZEL), which were fixed to the experimental apparatus equipped with a two-dimensional dynamometer, were cut. The normal (N) and frictional (F) forces acting on the rake face were measured. Using these components, the frictional coefficient (μ) on the rake face was calculated by μ=F/N. The effects of the distance (l_R) from the outer layer in the radial direction of the internodes of bamboo culms and cutting directions, as shown in Fig. 3,on μ were clarified.
