“…When machining titanium alloy blades, abrasive belt grinding can prolong the fatigue life of the blade, but it will also affect its performance. Xiao et al [ 8 ] used ABAQUS to establish a simulation model of titanium alloy grinding and analyzed the effect of grinding process parameters on the action law of surface residual stress; the final simulation results are consistent with the actual experiment results. Kaifa et al [ 9 ] established 3D finite element models associated with two original surface roughnesses as well as without original surface roughness based on Gaussian distribution combined with exponential autocorrelation function and performed integrated coupled DEM–FEM simulations of the shot peening process for these three target models to study shot peening residual stresses.…”

The disc-milling method is expected to increase the grooving efficiency of blisks. However, there are few studies about the residual stress on a blisk during disc-milling grooving. In this study, a single-factor experiment and an orthogonal experiment of blisk disc-milling and grooving were designed to obtain the residual stress. Surface subsurface residual stress were also studied. The results showed that the surface of the milling groove bore compressive stress. Residual stress decreased with increasing spindle speed and increased with increasing feed speed and spindle rotation angle. Moreover, residual stress was most sensitive to spindle rotation angle and least sensitive to feed speed. A higher residual stress produced on the machined surface led to a deeper layer of residual stress.

“…Previous research has primarily focused on investigating the impact of process parameters on residual stresses and mechanical properties. Specifically, these studies have examined the effects of cutting [4,5], annealing [6,7], milling [8], and grinding [9]. Through experimental studies, Wu and Matsumoto [10] discovered that the change in residual stress pattern is primarily related to the shear angle during chip formation.…”

γ-TiAl alloys are the most promising lightweight high-temperature structural materials, but the materials often fail from the surface, which is mainly attributed to the stress state of the material surface. In this paper, the orthogonal experiment method and molecular dynamics modeling are used to choose a set of the best process parameters for supersonic fine particle bombardment. Furthermore, by determining the optimal process parameters, this study examines the influence of residual stress distribution on the mechanical properties of the material under various process conditions. The simulation results reveal that the residual stress distribution is minimally impacted by particle radius, nonetheless, maintaining a moderate level of compressive residual stress within a specific range can substantially augment both the tensile strength and indentation hardness. An increase in the number of particles results in a more uniform distribution of surface residual stresses. Conversely, an increase in the number of impacts causes stress concentration to intensify at the particle's contact point, and thus a deeper distribution of residual stress is observed. This study illustrates how the mechanical properties of polycrystalline γ-TiAl alloy are affected by the process parameters of supersonic fine particle bombardment in terms of atomic size in order to develop and select the optimal supersonic fine particle bombardment parameters.

In this study, a CBN liquid-body-armor-like grinding wheel was developed for high-shear and low-pressure (HSLP) grinding of Inconel718 alloy. The material removal mechanism of the novel CBN liquid-body-armor-like wheel was introduced in detail. Particle clustering effect of the new wheel was studied via the finite element method. A series of grinding tests were carried out to investigate the grinding performance under the various conditions. It was shown that the surface roughness Ra of the ground workpiece decreased from initial 0.3 to 0.094 μm. Simultaneously, the specific material removal rate of 1.069 × 105 μm3/mm·s was attained. The power spectral density function (PSDF) was employed to reveal the percentage of waviness and roughness of the surface profile, which was mainly concentrated in 0–40k Hz as compared with 60–120k Hz before grinding. It indicated that particle clustering effect was generated in the grinding zone. Besides, the maximum peak amplitude of the cross-correlation function coefficient of the ground workpiece surfaces before and after grinding was less than 0.3. The original scratches were completely removed. New and smooth textures generated after grinding. The experimental results demonstrated that the newly developed CBN liquid-body-armor-like grinding wheel was effective for surface finishing of the Inconel718 workpiece.
