The results of a photographic technique for the determination of the complete temperature distribution in the orthogonal metal cutting process are presented; they are found to disagree with previous theoretical predictions. The temperatures along the tool rake face are of particular interest because they are thought to affect the wear of the cutting tool and friction between the chip and tool; it is found that these temperatures have been considerably over-estimated by previous work. By introducing the width of the secondary deformation zone, i.e. the extent of sub-surface deformation due to friction at the tool-chip interface, as a new variable, it is found that more consistent predictions of rake face temperatures can be made. From this work information has been obtained on the shape of the zones of plastic deformation in metal cutting and on the distribution of heat generation within these zones.read more

Shear angle solutions in orthogonal machining
TL;DR: In this article, it is shown that the effective shear angle will be smaller at slow speeds, for given values of tool rake angle and tool-chip interface friction, than at high speed sowing to the increase in width of the deforming zone with decrease in cutting speed.

The Influence of Rate of Strain-Hardening in Machining:
TL;DR: In order to determine the influence of the rate of strain-hardening (that is, rate of increase of flow stress with straining) on the machining process, cutting tests were carried out on a material as mentioned in this paper.
