“…Cryogenic grinding with cold air Choi et al [161,162] investigated the grinding process of the spindle shaft steel materials SCM4 and SCM2 under the compressed cold air condition, which was produced through a constanttemperature water bath and vortex tube. The compressed cold air has been found very effective in minimizing the thermal defects on the ground surface.…”

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.

“…Various theories have been proposed to explain this phenomenon by experimental, analytical and numerical studies. Hilsch suggested that the expansion of air from high pressure near the wall to low pressure near the axis generates a velocity gradient in radial direction which results in transfer of kinetic energy by the viscous force from the inner uid layers to the outer uid layers [1,2]. A Ranque-Hilsch * corresponding author; e-mail: semihyuksel@yandex.com Vortex Tube (RHVT) consists of one or more inlet nozzles, a vortex chamber, a cold-end orice, a hot-end control valve and a tube.…”

“…Liu and Hou applied VT cooling in steel turning and claimed that VT cooling may reduce crater wear, ank wear, and the ank wearrate [7]. Choi et al reported that VT cooling is capable of reducing surface roughness and generating compressive residual stresses at the workpiece surface in cylindrical grinding [2]. Nguyen and Zhang combined VT cooling and oil mist during surface grinding and demonstrated that a small amount of vegetable oil adds lubrication to cold-air cooling and improves the material removal rate under identical part quality constraints [8].…”

Controlling the heat, generated during the cutting process, is an important factor in improving the quality of the product and performance of the machining. A vortex tube was employed to evaluate the eects of cooling on the turning parameters. Various cutting parameters (100 m/min, 250 m/min and 400 m/min) together with various cooling temperatures (4• C, 8• C and 20• C) were considered to nd surface roughness, cutting force and cutting temperature. Response surface methodology was used to optimize the experimental parameters. The best attainable surface roughness value was found to be 0.77 µm Ra, under the conditions of 0.15 mm/rev feed, 400 m/min cutting speed, 4• C (with vortex tube) cutting temperature and 1.2 mm tool edge radius. Cutting forces were not aected by the temperature changes. The dierence was negligible and as small as 1%. The minimum cutting temperature was 74.17• C, which was obtained under the machining conditions of 0.25 mm feed, 250 m/min cutting speed 4• C (with vortex tube) cutting temperature and 0.8 mm tool edge radius.
