A contribution to a qualitative understanding of thermo-mechanical effects during chip formation in hard turning
TL;DR: In this paper, it was shown that serrated chip formation is the result of a softening phenomenon simulated by using Abaqus/Explicit software, and a parametric study was proposed of thermal properties such as variations of contact conductance and the fraction of frictional work converted to heat at the tool/workpiece interface.

An experimental and coupled thermo-mechanical finite element study of heat partition effects in machining
TL;DR: In this article, the authors used a fully coupled thermo-mechanical finite element model to evaluate the sensitivity of the model output to the specified value of heat partition, and showed that the accuracy of finite element models, such as chip morphology, toolchip interface temperature, von Mises stresses and the tool-chip contact length, is significantly dependent on the value of the heat partition.

An Evaluation of Chip Separation Criteria for the FEM Simulation of Machining
J. M. Huang,J. T. Black +1 more
TL;DR: Different chip separation criteria for the FEM simulation of machining were examined in this article, and the results showed that the chip separation process did not significantly affect chip geometry and distributions of stress in the chip, but it did affect the process of chip separation, distribution of stress and strain in the machined surface, and distribution of effective plastic strain both in chip and in the workpiece.
