“…Then, during machining steps, turning and gear hobbing modify residual stress distribution and distortion [7]. As a consequence, residual stress can be considered in this study as a major factor of distortion [8]. Thus, among all carriers of distortion potential described in Fig.…”

“…12. The neutralization that has been chosen is the same as previously: a 4-h 600 • stress relief (designated by "SR") [8]. Eight lots are considered: one lot without any stress relief and seven lots that are stress relieved once during their manufacturing history.…”

“…Neutralization for lot B is applied through a 4-h 600 • C stress relief under a low-pressure atmosphere. This stress relief has been chosen because it enables to decrease the levels of superficial residual stress from 300 MPa to less than 150 MPa in absolute value, which is less than 20 % of the rupture stress of the studied steel [8]. Thus, the residual stress level is hypothesized as not significant after the 4-h 600 • C stress relief.…”

International Journal Advanced Manufacturing Technology, 2014, 72 (9-12) As a consequence, geometrical nonconformities roots can be determined more easily thanks to this diagnosis tool, and corrective actions can be applied. Secondly, the influence of product geometry on bending is experimentally considered. Moreover, metallurgical observations enable to explain the influence of workpieces geometry on shaft bending. Thanks to the obtained results, process and product recommendations to decrease shafts bending are proposed.

“…In that case, grinding operations are insufficient to compensate these deformations and consequently to permit satisfying the functional geometrical tolerances imposed by the designer. The distortions of the parts must therefore be anticipated before the treatment, yet today still, at the cost of expensive and time consuming experiments carried out with physical demonstrators [2]. In the case of nitrided thin walled components (thicknesses of a few millimetres), significant tensile residual stresses are also generated in the core of the material to balance the surface compressions created by the thermo-chemical treatment.…”

The simulation of a complete manufacturing process to produce an aero engine case, including forging, rolling, and machining processes, is analyzed via finite element software. The deformation of the turning and drilling processes is quantitatively studied using the energy principles. Firstly, simulations of multi-stage forging of aero engine case and machining-induced residual stress are conducted and verified via the residual stresses test in order to provide the initial elastic strain energy condition prior to machining processes. The effects of blank forging-induced residual stress and machining-induced residual stress on the deformation of titanium alloys aero engine case are investigated. Secondly, a potential energy expression for the machining processes is developed. The predicted results of turning and drilling simulations indicate that there is an optimal process in which the deformation and potential energy decline rapidly compared with the other processes and finally, gradually stabilize at the end of the process.
