Estimates of the bistable region in metal cutting
, 2008 The classical model of regenerative vibration is investigated with new kinds of nonlinear cutting force characteristics. The standard nonlinear characteristics are subjected to a critical review from the nonlinear dynamics viewpoint based on the ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes
FEBS Open Bio, EarlyView.Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Some Effects of the Cutting Fluid on Cutting Force
Journal of the Japan Society of Precision Engineering, 1966 各種の組成を有する切削油剤を用いて, 切削油剤の潤滑効果と冷却効果が, 切削抵抗に及ぼす影響を調べた。超硬バイトによる車軸鋼の切削の場合につき, 普通鋼の高温における機械的性質の変化を考慮に入れて考察した。またそれらに関連して, 切削油剤の作用について, 定性的に一般的考察をした。1) 削り速度20m/min～40m/minにおいては, いずれの切削油剤も有効であるが, 中でも, 極圧潤滑性に富むものの方が, 冷却性に富むものより有効である。水だけでも明らかに切削抵抗を軽減する作用はあるが, その変動係数は比較的大きく, 特に, 削り速度20m/minの場合には, 乾切削の場合よりも大きい。2) 削り速度40m/min以上においては, 塩素系添加剤のものは効果を失い, かえって切削抵抗は高くなる ...

Influence of Cutting Interactions on Cutting Force of a Pick
AASRI Procedia, 2012 Abstract Various mechanical excavators have been used for rock cutting. The cutting drum of an excavation machine normally consists of a large number of cutting picks. Accurate calculation of cutting force on individual picks is important to machine design and control. In rock cutting, cuts between picks can interact with each other.
