Chapter 5 – Heat in metal cutting
TL;DR: In this article, the role of heat in limiting the rate of metal removal when cutting the higher melting point metals is discussed. But, as pointed out, there is no direct relationship between cutting forces or power consumption and the temperature near the cutting edge, and the most important heat source responsible for raising the temperature of a tool is the flow-zone where the chip is seized to the rake face of the tool.

Cutting mechanism during machining of hardened steel
TL;DR: AISI 4340 steel was machined on an engine lathe to study chip morphology, tool forces, and the surface generated as discussed by the authors, and it was found that chip segmentation occurs when the hardness of the steel exceeds a certain value.

Predictive models for flank wear on coated inserts
TL;DR: In this paper, a set of experiments was performed to understand the effect on flank wear due the morphology and amount of the second phase in work materials, and they developed predictive models for flank wear that explicitly incorporate cutting temperature and the physical properties of coatings and work materials.

Micromechanisms of tool wear in machining free cutting steels
K. Ramanujachar,S.V. Subramanian +1 more
TL;DR: In this article, a quantitative investigation of tool crater wear was carried out in free cutting steels with and without lead addition (commercial grade AISI 12L14 and AisI 1215 respectively) at moderately high cutting speeds (140-220 m min −1 ) using cemented carbide cutting tools.

Effects of plastic deformation on carbide precipitation in steel
TL;DR: The influence of plastic deformation on carbide precipitation in carbon steels containing 0.47, 0.74, and 0.88% carbon has been studied, using electron microscopy and magnetic analysis as discussed by the authors.

Some recent research on the wear behaviour of carbide cutting tools
H. Opitz,M. Gappisch +1 more
TL;DR: In this paper, it was shown that the most favorable cutting conditions, from the point of view of wear, occur only if no built-up edge exists, and that in order to obtain good machinability, the most favourable structural states are those which result in an austenite phase with little carbon at the back of the chip.
