Study of Soft Tissue Cutting Forces and Cutting Speeds
2004A versatile equipment to study the cutting of soft tissue with surgery scalpel was designed and constructed. Experiments were performed with pig liver (ex-vivo) to measure the blade-tissue interaction forces at cutting speeds ranging from 0.1 cm/sec-2.54 cm/sec. The experimentally measured force-displacement curves reveal that the liver cutting process

The magnitude of cutting forces at high speed
The Journal of Prosthetic Dentistry, 2003Previous research has used a range of cutting forces for preparing teeth, but there are no data available on the forces actually imposed while cutting teeth with high-speed handpieces.The purpose of this study was to measure the forces imposed while cutting teeth with tungsten carbide burs used in high-speed handpieces.Thirty-one dentists each cut 8 ...

Studies on dental high‐speed cutting
Journal of Oral Rehabilitation, 1995summary The primary author, an experienced dentist, cut bovine enamel and dentine horizontally and vertically with diamond points driven by an air‐turbine, while the rotational cutting speeds and applied loads were simultaneously monitored. Three cutting techniques employed here were successive cutting with moderate force (S‐m); intermittent ...

Cutting Experiments in Cutting Speeds of up to 200 m/s with a High-Speed Impact Cutting Tester
Key Engineering Materials, 2012High-speed orthogonal cutting experiments with cutting speeds of up to 200 m/s with a high-speed impact cutting tester of air-gun type are attempted. In this tester, a light projectile with a small built-in cutting tool is loaded into a tube, being accelerated by a compressed gas.

Effects of Friction and Cutting Speed on Cutting Force
Manufacturing Engineering, 2001Abstract Observations are made regarding the influence of cutting speed and friction on cutting force by way of finite element modeling. Simulations are validated by comparison of cutting forces and chip morphologies for the A16061-T6. Analysis of cutting forces over a wide range of cutting conditions suggests an important role of the ...

In certain contexts, high speed cutting is only defined as machining at high cutting speeds (spindle speeds) and/or at high feed rates in order to achieve short machining- or lead times. However, for a reasonable classification, one has to consider the material to be machined (soft- or hard machining), the cutting materials and the metal removal rate.

Honing with increase in the cutting speed
Russian Engineering Research, 2008The honing methods with constant tool speed currently employed do not fully utilize the potential of each abrasive grain and the tool as a whole in producing high surface quality [1, 2, etc.]. Variation in speed of the honing head is proposed to permit more complete utilization of the tool’s potential, reduce tool wear, and improve the quality of the ...

Speed effects in cutting and ploughing
Géotechnique, 1999A significant speed effect occurs when blades and ploughs cut saturated soil. The cutting force increases dramatically with cutting speed, sometimes by a factor of five or more. In some soils, the effect occurs at very low speeds. It has significant practical implications, and has caused difficulties in several projects. The effect is explained by the

High-speed cutting of foods: Cutting behavior and initial cutting forces
Journal of Food Engineering, 2018Abstract The viscoelastic properties of foods determine deformation, fracture and friction during industrial cutting applications and substantially affect the cutting behavior, especially at high cutting velocity. Using a custom-built high-speed test station the cutting behavior of representative foods (either based on a protein network, plant ...

A study of oblique cutting for different low cutting speeds
Journal of Materials Processing Technology, 2001Abstract In this paper, the finite deformation theory and an updated Lagrangian formulation (ULF) were used to describe the oblique cutting process. Either the tool geometrical location condition or the strain energy density constant was combined with the twin node processing method to be adopted as the chip separation criterion.
