機械加工能率を向上させた腰掛蟻仕口の強度特性に関する研究: 寸法•形状の変化が強度特性に及ぼす影響

摘要

The shape of commercial dovetail joints, which is machined with precut system, is not suitable for machining. This form has the disadvantage that cannot be machined in a single pass. In this paper, we proposed a variant of the weaknesses of its shape. Conducted shear tests and tensile test, we discussed the relationship between the shape and the strength properties . In addition, we compared the performance of the experimental values with the calculated value by the current design equations.%プレカット加工された腰掛蟻仕口の機械加工能率を向上させる改良を施した形状について，縮尺モデルで寸法•形状と強度特性間の関係を検討した。さらに実大モデルに適応して改良形状の強度特性を確認した。
