“…However, it was found that the Finite element model has some limitations. Majority of the works are using the orthogonal cutting model to predict the residual stresses [14][15][16]], but there is certain level of drawback in such models, when it comes to machining, it is invariably oblique cutting which is happening, but it is assumed that orthogonal cutting takes place for simplification purposes. As mentioned earlier the authors of the present work have developed a 3d model, which closely captures the oblique cutting.…”

Residual stresses prediction has been challenge over the years. Many models have been developed in order to predict the residual stresses. Research has been taking place in this field since many decades. Numerical, experimental as well as analytical models have been developed to determine the nature and magnitude of the residual stresses. In the present work, the authors have made an attempt to build a mathematical model using statistical techniques.The difference between the predicted and the experimental values are in good agreement and the error percentage is less than 15%. The statistical parameters required to ascertain that the developed model are in good agreement to the standard values. The novelty of the work is that, proper procedure has been followed to ensure that the residual stresses induced by the primary manufacturing processes to prepare the specimen is made minimal so that the results are not biased. The future work of the work is to optimize the machining parameters using optimization techniques for which the mathematical model developed in this work will serve as the objective function.

“…The quality and the functional behavior of the machined components are greatly affected by the induced residual stresses (RSes) state in the surface and subsurface layers. Depending on the attributes of the induced RSes state, RSes can be either beneficial (compressive RSes) or detrimental (tensile RSes) to the performance of machined components [1]. It is well known that tensile RSes in the surface and subsurface layers are usually detrimental to fatigue life [2], creep life [3], and stress corrosion cracking resistance [4], while compressive RSes are usually beneficial to the same properties [5].…”

Residual stresses (RSes) induced by turning processes have a great effect on the material properties of the machined components and their abilities to withstand severe loading conditions (creep, fatigue, and stress corrosion cracking). The final state of RSes in a workpiece depends on its material and on the employed cutting parameters/conditions such as cutting speed, depth of cut, feed speed, cutting tool geometry, wear of the tool, cutting tool geometry, cutting tool coating, and cooling. This study introduces a comprehensive investigation of the effects of different cutting parameters, such as cutting speed (30, 60, and 90 m/min), feed (0.05, 0.1, and 0.3 mm/rev), and depth of cut (0.1, 0.5, and 1 mm) as well as cutting tool geometry such as cutting tool nose radius (0.397, 0.794, and 1.191 mm), and cutting tool coating (coated and uncoated) on the cutting force, maximum cutting temperature, surface microstructure, and surface residual stresses during cutting AISI 1035 alloy steel. The RSes were measured using X-ray diffraction technique. The experiments were designed using Taguchi method based on L 18 orthogonal array, and the significance level of different cutting parameters as well as cutting tool properties have been determined via applying analysis of variance. Numerical simulations have been carried out using commercial machining software AdvantEdge.

“…Fatigue life prediction of components is an important issue in engineering applications and could be extended by the near-surface macroscopic compressive residual stresses that retard fatigue crack initiation and crack growth. Major fatigue life prediction methods modify the fatigue limits to account for the presence of residual stresses [1][2][3][4][5][6][7][8][9][10]. The compressive residual stress resulting from the different surface treatments such as shot peening, carburizing, nitriding, have a favorable effect on the resistance of fatigue crack initiation [3,7,[10][11][12].…”

“…The residual stresses are decreased and redistributed through a process called relaxation. The residual stresses are the key factor for fatigue strength improvement; however, mechanical load redistributes and relaxes the beneficial compressive residual stresses [3,4,6,10,11].…”

Initial compressive residual stresses, induced by ionic nitriding treatments, relax during component operating life and it is important to consider the relaxation phenomenon in the design of the component. The paper presents three analytical models (Seungho Han et al., Zaroog and Kodama) to estimate the level of residual stress after cyclic loading. The initial and final residual stresses has been measured after each loading cycle for many load magnitudes using x‐ray diffraction. It was found that about 40 %–50 % of the maximum residual stresses are relaxed during the first cycle. The reduction in the residual stress, are dependent on the applied load because of the plastic deformation caused by the superposition between the nitrided residual stress and the applied load. It was found that the estimated average values by analytical models are comparable with the results of experimental studies after cyclic loading.
