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

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.

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 ...

Cutting high-performance materials with ultrasonically modulated cutting speed
Seventh European Seminar on Precision Optics Manufacturing, 2020The continuing trend towards lightweight construction and the associated machining rates of up to 95 % lead to an increased use of high-performance materials. The ever growing demands on the strength and quality of components and the associated use of materials which are hard to machine require the further development of new, economical machining ...

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.

Cutting Speed in Nano-Cutting as MD Modelling Parameter
International Journal of Manufacturing, Materials, and Mechanical Engineering, 2016In order to manufacture parts with dimensions of nanometres, high–technology equipment is required. There is a demand to study nano-metric cutting mechanisms and phenomena appearing in this level. However, experiments are difficult to be realized, so computational methods are employed.

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 Chapter 8, operation planning was analyzed. It was shown that selecting an operation plan is not an independent decision; it depends on the selected depth of cut. However, the decision of selecting a depth of cut was partially based on the feed rate decision.

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
