“…The generation of residual compressive stress can inhibit the formation of surface microcracks, which effectively improve the surface mechanical properties of parts, improve fatigue resistance and extend service life. Shen et al 9 studied the residual stress variation law of C-250 martensitic failure steel after grinding processing, and obtained the residual stress distribution on the surface and subsurface of the part. Wu et al 10 used the finite element method to analyze the residual compressive stress distribution of ultrasonic surface rolling process (USRP) single-point impact of 40Cr steel, and found that when the amplitude was 12 μm and the static pressure was 600 N, the residual compressive stress was the largest.…”

To obtain the distribution law of residual stress of 42CrMo steel processed by ultrasonic rolling extrusion process (UREP), according to the characteristics of the material treated by ultrasonic rolling extrusion process, 42CrMo steel quasi-static experiment and dynamic experiment are carried out, the improved Johnson–Cook model was proposed. Based on the 42CrMo constitutive equation, the ultrasonic rolling extrusion process finite element method and experiment of 42CrMo steel were carried out. The results show that the simulation value and experimental value of the residual stress distribution after ultrasonic rolling extrusion process of 42CrMo steel have good consistency, with the increase of static pressure and amplitude, the residual stress increases, and with the increase of rotational speed and feed speed, the residual stress decreases, a more accurate residual stress distribution law of ultrasonic rolling extrusion of 42CrMo steel is obtained.

“…They showed that surface roughness decreases by increasing the size of abrasive grits. In a study conducted by Shen et al 15 it was shown that distribution of residual stresses and maximum compressive stress are highly dependent on the cutting speed in abrasive machining processes. Buj-Corral et al 6 studied the residual stresses in rough, semi-finish, and finish honing processes on hardened steel cylinders using cubic boron nitride (CBN) abrasives.…”

“…Furthermore, in these conditions, the hook-shaped curve of the stress diagram shifts toward the outer-layer of the cutting surface, indicating that the depth at which the maximum stress is induced shifts toward the surface of the sample. 6,15 On the other hand, for numerical simulation of machining processes, several constitutive plastic models, such as Power-Law and Johnson-Cook models, introduced. The J-C model has been widely used in numerical simulations of metal cutting processes to predict the residual stresses at the machining surfaces of the samples.…”

Super polishing methods are widely employed to improve the surface integrity of machined parts. These methods not only improve the surface texture of the machined parts, but also modify the residual stresses induced at the outer layer of the machined surface. In this study, the effects of honing process parameters on the distribution of residual stresses at the surface of grey cast iron investigated numerically and experimentally. To this aim, a finite element (FE) model developed to evaluate the effects of process parameters, including cutting speed, grain size, and pressure of honing tools, on the residual stresses induced at the surface of samples. The friction coefficient introduced as an updating parameter in the model to get the best correlation between the results of FE and experiments. In addition, the X-ray diffraction method used to experimentally measuring the distribution of residual stresses at the honing surface of the samples. The experimental and numerical results showed that in majority of combinations of the process parameters, the maximum compressive residual stress occurs at a depth of approximately 0.03 mm from the cutting surface of the sample. Additionally, it was seen that decreasing the size of abrasive grains and cutting speed and increasing the pressure on the cutting tool result in higher levels of induced compressional stresses at the surface of samples. However, the depth at which the maximum residual stress occurs can proceed up to 0.06 mm by an increase in the diameter of abrasive grains and cutting speed.

“…Denkena et al [3] investigated the in uences of grinding with Toric CBN grinding tools on the residual stress and got the conclusion that a good surface nish could be achieved with small cutting grain size, low feed rates and frontal grinding strategy. Shen et al [4] studied the surface and subsurface residual stress distributions in ground C-250 maraging steel (3J33) after the grinding process and the results showed that the surface residual stress and peak compressive residual stress depend greatly on the grinding speed and the residual stress penetration depth increases with the increase of the grinding speed and grinding depth and decreases with the increase of the workpiece speed while the depth of peak compressive residual stress varies slightly with the grinding parameters. Zhao et al [5] researched the effects of contact surface friction, grain's tip radius, grain's protrusion depth, and grain's rake angle on residual stress distribution after abrasive belt rail grinding (ABRG) based on ABRG test beach and 3D nite element model (FEM).…”

Large-width Cam has been widely used in high-power marine diesel engines, due to its well strength, wear-resisting, and service life. Unlike the traditional cam, the large-width Cam must be ground by swing grinding process to avoid grinding defects caused by high machining temperature. As the in uence of swing grinding parameters on machining surface quality has not been clearly clari ed, experimental study was discussed in the paper. The orthogonal experiment was designed and based on which the residual stress, surface roughness and hardness were analyzed. The results showed that, the grinding depth and the cam speed, have a relatively great in uence on the residual stress compared with grinding wheel swing frequency and swing amplitude. The grinding wheel frequency has the greatest in uence on the hardness of the cam surface and the increment of it will increase the hardness of the Cam.
