Effects of Specific Gravity in Air dry Condition upon Cutting Phenomenon, Stress Distribution over Tool Rake Face and Frictional Coefficient on Interface between Tool and Chip in Orthogonal Cutting of Wood

In order to make clear the cutting mechanisms which are related to cutting forces, tool wear, machinability of workpice, cutting efficiency and so on, a more fundamental research under the actual cutting conditions should be carried out. For that purpose, it is important and necessary to make clear the actual stress distributions on the tool rake face. But few studies have dealt with the exact measurements of the stress distributions, and so, the main objective of this study is to obtain quantitaive information on them. In this study, the basic orthogonal cutting tests of wood were performed at 144.9 mm/min of cutting speed under various combinations of depth of cut (t) and specific gravity of wood in air dry condition (ru), using the conventional tool and the composite tool in order to make clear the influence of two factors on the cutting force components, the cutting phenomena, the stress distributions over the tool rake face and the frictional coefficients on the interface between the tool and the chip. The main results obtained are summarized as follows: (1) The distributions of the frictional stress (r) and the normal stress (o) over the tool rake face can be expressed by Eq. (7), and the variations of the values of the exponents and the coefficients used in this equation with ru are illustrated in Figs. 9 and 10. (2) On the basis of the experimental results (Eqs. (2), (3) and (5), and Figs, 8 and 9) obtained in the wood cutting tests, the cutting force ratios on the tool face near the tool edge to the total cutting force on the tool face can be calculated from Eq. (9), and these ratios are shown in Tables 2 and A-4. (3) The frictional coefficients (μ3) on the tool rake face can be expressed by Eq. (15). On the tool rake face,μ3 can be considered to be constant, and the values of μ3 are shown, comparing with the other frictional coefficients, in Fig. 12, Tables 3 and A-5

和歌山県, 奈良県および三重県における作物在来種の調査と収集

Exploration mission was undertaken in Wakayama, Nara and Mie prefectures from November 1 to 6 in 1998. A total of 73 seed samples which belong to 12 plant species were collected during the exploration. Seed samples collected include 26 of soybean (Giycine max), 15 of azuki bean (Vigna angularis), 10 of kidney bean (Phaseolus vulgaris), 2 of cowpea (Vigna unguiculata), 1 of peanuts (Arachis hypogaea), 4 of proso millet (Panicum miliaceum), 3 of sorghum (Sorghum bicolor), 3 of maize (Zea mays), 3 of wheat (Triticum aestivum), 2 of barley (Hordeum vulgare), 2 of foxtail millet (Setaria italica) and 2 of sesame (Sesamum indicum). Landrace of soybean varied in seed coat color (yellow, pale green and black) and crop season (spring and summer sowing). They are mainly used as the material of "ni-mame" (beans cooked with sugar). Some farmers also make miso (fermented soybean paste) from cultivars with yellow or pale green seed coat. Formerly, farmers maintained three types of azuki bean with different crop seasons adapted the various kinds of cropping system, although most of them have already disappeared. Their main use is the material for "seki-han" and "anko" (sweet paste). Landraces of kidney bean varied in the shape of the seed, seed coat color and vine type. They has been mainly used for making "ni-mame", while young pods are boiled and used as a vegetable. All the samples of sorghum and millets are glutinous and are used for making "mochi" (glutinous rice cake with millet flour). Sorghum is called "takakibi" or "kibi", whereas proso millet (Panicum miliaceum) was referred to as "inakibi" or "komekibi", which means millet resembling rice grain. Two samples of wheat and barley were also collected, they are cultivated to make malt for miso. Most of the local cultivars maintained in mountainous regions of Mie, Nara and Wakayama prefectures were legumes such as soybean, common bean and azuki bean. Cultivation of millets remains mainly in Totsukawa and neighboring villages
