Modeling the Forces of Cutting With Scissors [PDF]
IEEE Transactions on Biomedical Engineering, 2008 Modeling forces applied to scissors during cutting of biological materials is useful for surgical simulation. Previous approaches to haptic display of scissor cutting are based on recording and replaying measured data. This paper presents an analytical model based on the concepts of contact mechanics and fracture mechanics to calculate forces applied ...

Prediction of sand mold cutting force and identification of cutting force coefficients
Journal of Physics: Conference Series, 2021 Abstract Patternless casting technology is an advanced digital forming technology. Sand mold cutting is one of the most important techniques of patternless casting technology. In the process of sand mold cutting, the cutting force is the key factor affecting the quality of sand mold machining, and is an important prerequisite for the ...

Forces and Plastic Work in Cutting
CIRP Annals, 1983 Prolific considerations in C.I.R.P. give rise to a further step in the development of a plastic cutting model. Basically two different primary shear zone geometries are assumed: with one and with two shear planes respectively. For both geometries two energetically different approaches are developed.

Cutting Force Estimation Considering the Specific Cutting Force Constant
Journal of the Korean Society of Manufacturing Process Engineers, 2019 Few studies have been conducted regarding theoretical turning force modelling while considering cutting constant. In this paper , a new cutting force modelling technique was suggested which considers the specific cutting force coefficients for turning.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1987 As the cutting condition of generating gears such as in hobbing is very complex, the specific cutting forces are different from those of orthogonal turning. In general, the specific cutting forces in hobbing are large, since the flowing chips interfere on the tool face.

Cutting Force Control Applying Sensorless Cutting Force Monitoring Method
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010 Intelligent machine tools require the functions of high-accurate process monitoring and adaptive control to fit the optimum process condition in each workpieces. For realizing these functions, the various techniques to monitor the cutting process and control it using additional sensors have been proposed and widely studied.

Predictive Cutting Force Model and Cutting Force Chart for Milling with Cutter Axis Inclination
International Journal of Automation Technology, 2013 A force model for milling with cutter axis inclination is presented. The model predicts the cutting force and chip flow direction. Three-dimensional chip flow is interpreted as a piling up of the orthogonal cuttings in the planes containing the cutting velocities and the chip flow velocities in the inclined coordinate system with a ball end mill.

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.
