Effect of Cutting Speed on Chip Fracture Strain in High Speed Cutting

Materials Science Forum, 2009
This paper deals with the effect of cutting speed on chip fracture strain in high speed cutting. Firstly, a chip-fracture-strain-measuring device is designed and made according to chip breaking principle. Secondly, experiments are performed by the chip-fracture-strain-measuring device.

Cutting Speed in Nano-Cutting as MD Modelling Parameter

International Journal of Manufacturing, Materials, and Mechanical Engineering, 2016
In 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.

Maximum cutting speed in laser cutting of fiber reinforced plastics

International Journal of Machine Tools and Manufacture, 1988
Abstract A simple one-parameter thermal model, predicting the maximum feed rate still resulting in a through cut as a function of beam power, focal spot diameter and thickness of worked material is presented and discussed for CO 2 laser cutting of composites.

Aspects in Cutting Mechanism in High Speed Cutting

CIRP Annals, 1989
Summary Since appr. 10 years the researches on high speed cutting (hsc) are one of the scientific key points of the Institute of Cutting Technology and Machine Tools (ITW) of the Technical University of Darmstadt. One of the essential results is the fact that just known cutting mechanisms in normal speeds are also valid for hsc.

Plasma arc cutting: speed and cut quality

Journal of Physics D: Applied Physics, 2009
When cutting metal with plasma arc cutting, the walls of the cut are narrower at the bottom than at the top. This lack of squareness increases as the cutting speed increases. A model of this phenomenon, affecting cut quality, is suggested. A thin liquid layer, which separates the plasma from the solid metal to be melted, plays a key role in the ...

SPEED CUT

Alloy Digest, 1960
Abstract SPEED-CUT is a free-machining medium carbon die steel having air hardening properties. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on forming, heat treating, machining, and joining.

Studies on dental high‐speed cutting

Journal of Oral Rehabilitation, 1995
summary 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 ...

Study of Soft Tissue Cutting Forces and Cutting Speeds

2004
A 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, 2003
Previous 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 ...
