“…Taking into account that the steels with higher ferrite content achieved longer l c , in spite of their lower strength and possibly lower normal pressures, their F c or K sc was the same as the C45 and C60 steels. With regards to the results of K sf , the greater values measured in the steels with higher ferrite content were in line with the literature [6,29].…”

“…Obikawa et al [24] detected the relationship between the grinding-induced residual stresses and the metallurgical microstructure of steel materials and found that the residual stress on pearlite is about twice larger than that on ferrite. The average residual stress all over the ground surface and that only on pearlite increases with the volume fraction of pearlite.…”

“…For this reason, characterization and prediction of grinding-induced residual stresses have been vital to the advanced design and fatigue failure analysis of components for aerospace, aviation, and automotive applications [23]. If grinding-induced residual stresses are not quantitatively known, the reliability of a component is hard to be guaranteed [24]. As such, the optimization and control of residual stress distributions have been one of the most important research aspects in the grinding community [25,26].…”

This paper provides a state-of-the-art review on the investigations into the residual stresses in metallic structural materials generated by grinding. The materials covered include steels, titanium alloys, and nickel-based superalloys. The formation mechanisms of the residual stresses and their impacts are specifically discussed. Some major influential factors on the residual stresses formation in grinding, such as grinding wheel characteristics, dressing techniques, grinding parameters, cooling conditions, and properties of workpiece materials, are analyzed in detail. These include experimental measurement, modeling, simulation, knowledge-based monitoring, and fuzzy analysis. Finally, the paper highlights some important aspects of grinding-induced residual stresses for further investigation.

“…This has allowed for more accurate simulations at the levels of chip formation, temperature fields and cutting forces. The same procedure was used by Obikawa et al [15] Cutting speed parameters. Mohammed et al [16,17] developed a cutting model that takes into account the effect of the microstructure of compacted graphite iron on chip formation.…”

The development of computation means has allowed the simulation of complex mechanical problems. The first simulations of manufacturing processes at the microstructure scale, namely in the field of machining, have recently emerged. In this study, and on the basis of previous research, a novel approach to machining simulation is proposed. A crystal plasticity behavior law has thus been implemented and its parameters have been identified, for each of the two phases constituting the material. This is achieved through experimental tests conducted under extreme conditions of temperature and strain rates. Numerical models are composed of grains in the form of Voronoï cells. Random crystal orientations have also been assigned to each grain. This has subsequently allowed the simulation of the machining process. Access to local physical parameters such as crystal orientations, their evolution and phase transition thus presents a major breakthrough in this field.
