“…Meanwhile, according to an experimental comparison of residual stress produced in coarse grinding of steel rolls, as displayed in Fig. 19, Podgornik et al [138] found that the workpiece surface layer is left with large tensile residual stress up to 400-1000 MPa in the case of dry grinding, which extends into the depth of about 1 mm; however, water cooling results in the reduced residual stresses and faster drop in stresses by depth. Moreover, when the grinding feed is decreased from 80 mm/rev (water 1) to an appropriate value of <50 mm/rev (water 2), the transformation tendency of residual stress from a tensile state to a compressive one becomes significant.…”

“…Because the film boiling effect always blocks the transfer of the grinding heat into the coolant, the water-based grinding Fig. 19 Effects of dry grinding and wet grinding on residual stresses of ground components [138] fluid with higher heat transfer capability could not reduce the grinding temperature. As a consequence, compared with the grinding oil, the water-based grinding fluid could not produce any improvement in the residual stresses [91,146].…”

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.

Bimetallic rolls are widely used in hot rolling mills because of excellent hardness, wear resistance, and high temperature properties. Considerable residual stresses are produced for the bimetallic roll during quenching. Moreover, severe thermal stresses are caused by heating-cooling thermal cycles during subsequent hot rolling process. Fracture from the roll center may occur due to the residual stress adding to the thermal stress, and therefore, it is desirable to investigate the residual stress to improve roll service life. Therefore, FEM simulation of the bimetallic roll is performed for the quenching process. It should be noted that a large number of experimental data of the core and shell material are utilized for the wide range of temperature considering the quenching. The generation mechanism for the residual stress is discussed focusing on the effect of temperature gradient and phase transformation. Furthermore, the effects of shell-core ratio and diameter on residual stress are considered. Results show that the residual stress only slightly increases with increasing shell-core ratio, while significantly increases with increasing diameter.
