Influence of the tool edge geometry on specific cutting energy at high-speed cutting [PDF]

open access: yesJournal of the Brazilian Society of Mechanical Sciences and Engineering, 2007
This paper presents specific cutting energy measurements as a function of the cutting speed and tool cutting edge geometry. The experimental work was carried out on a vertical CNC machining center with 7,500 rpm spindle rotation and 7.5 kW power. Hardened steels ASTM H13 (50 HRC) were machined at conventional cutting speed and high-speed cutting (HSC).

Mechanical specific energy versus depth of cut in rock cutting and drilling

open access: yesInternational Journal of Rock Mechanics and Mining Sciences, 2017
Abstract The relationship between Mechanical Specific Energy (MSE) and the Rate of Penetration (ROP), or equivalently the depth of cut per revolution, provides an important measure for strategizing a drilling operation. This study explores how MSE evolves with depth of cut, and presents a concerted effort that encompasses analytical, computational ...

Estimating specific energy from the brittleness indexes in cutting metallic ores [PDF]

open access: yesJournal of the Southern African Institute of Mining and Metallurgy, 2016
Specific energy (SE) is a very useful parameter for assessing rock excavation by machine. Predicting the SE from the brittleness will be practical, especially for preliminary studies, due to the fact that determining the SE from cutting tests is difficult and expensive. In this study, the predictability of the SE from different brittleness concepts was
