Raising a cutting speed to above speed of a plastic wave of a workpiece material induces the high levels of the hydrostatic stresses in the shear zone, because a plastic wave traveling there becomes a shock wave. In order to ascertain the cutting phenomena occurring under the ultra high-speed cutting condition, the cutting experiments of a pure lead ...

Influence of Cutting Speed on Cutting Force in High-Speed Milling
Advanced Materials Research, 2010High Speed Milling (HSM) is well known as an innovative key technology for modern machining. HSM can obtain very high surface qualities, subsequent manually finishing operations can be eliminated in many cases totally or at least partially. Theoretical and experimental researches have proven that the cutting force in a high speed milling process has ...

Plasma arc cutting: speed and cut quality
Journal of Physics D: Applied Physics, 2009When 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 ...

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 ...

Ultra-Precision High Speed Cutting
2021Today, the technology of high speed machining (HSM) is well understood and established for conventional turning and milling at high material removal rates. However, this is not the case for ultra-precision processes. Consequently, in this project the mechanisms of high-speed machining in the ultra-precision range were investigated for both, non-ferrous

Maximum cutting speed in laser cutting of fiber reinforced plastics
International Journal of Machine Tools and Manufacture, 1988Abstract 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, 1989Summary 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.
