Abstract |
The data on metal cutting forces are required not only for the design of machine tools and cutting tools but also for the determination of cutting condition. Many researchers concentrated their efforts on the theoretical study and the empirical study for the prediction of the shear angle that dominates the cutting forces. In the orthogonal cutting tests of various materials under the cutting condition in the range of practical operation,the shear angle is shown to be strongly affected by the cutting speed and to be expressed with a simple empirical equation. However, since the empirical equation is not in sufficient agreement with the theoretical equation, it is necessary to develop the rule that dominates the shear angle. New consideration concerned with the propagation velocity of plastic deformation could be introduced. 金属切削における切削抵抗は,工作機械や工具形状設計のためだけでなく切削条件の決定のためにも必要である。多くの研究者により,切削抵抗に影響を及ぼすせん断角の予測について理論的,実験的検討がなされてきた。実用域の切削条件のもとで様々な材料の二次元切削試験が行われ,せん断角は切削速度に深く関係し,簡単な実験式で表されることが分かつた。しかしながら,これらの実験式と理論には十分な一致が認められず,せん断角を支配している要因をさらに解明する必要がある。そこで,塑性変形伝播速度という新しい観点からの考察を行う。 |
