The system employs a vibrating sonotrode that drives the formation and collapse of bubbles within a fluid medium. The imploding bubbles produce pressure waves which transfer momentum to the abrasives which are uniformly distributed in the fluid medium. The abrasives bombard a targeted surface along with intense pressure waves. This induces compressive residual stress through local plastic deformation in a short period. The capability of the ultrasonic-assisted abrasive peening setup is analysed in terms of residual stress by altering the abrasive concentration, peening time, and stand-of-distance between the bottom of the sonotrode and the exposed surface to be treated. The process is able to induce significant residual stress at around 67 % of yield strength for hard material Ti–6Al–4V and more than 80 % of yield strength for ductile materials, Al-6061 and OFHC-Cu. A numerical method coupled with a finite element model is employed to predict the dynamics of the process from cavitation of the bubble to the plastic deformation of the work material. At first, the model estimates the magnitudes of high-pressure waves at the bubble implosion near the solid surface, micro-jet velocity, and abrasive velocity. This information is then fed to Abaqus for numerical modelling of the deformation of work material. The impact of high-speed abrasives in the range of 100 m/s, pressure waves and microjets at the material surface are simulated through the FE model. The simulated results are verified with experimental findings in terms of surface residual stress for different materials, deviating within 10 %.</p></div>","PeriodicalId":14011,"journal":{"name":"International Journal of Machine Tools & Manufacture","volume":"194 ","pages":"Article 104100"},"PeriodicalIF":14.0,"publicationDate":"2023-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0890695523001086/pdfft?md5=5c2739c8f07add29b1e99273ec9b207a&pid=1-s2.0-S0890695523001086-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138438961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, the triply periodic minimal surface (TPMS) lattice structures with the same volume fraction from a normal Gyroid lattice to an octuple interlacing Gyroid lattice were prepared by the laser powder bed fusion<span><span> (LPBF) technique. The influence of the interlacing-cell number on manufacturability, uniaxial compression mechanical behaviors, and hyperelastic responses of Ni–Ti lattice structures are analysed by experiments. The stress distributions and fracture mechanism of multicell interlacing lattice structures are illustrated by the finite element method. The obtained results reveal that when the volume fraction is the same, the specific surface area of the lattice structure increases with increasing interlacing-cell number, and the </span>curvature radius<span> of the single-cell strut reduces, which leads to the decrease in the manufacturability of the lattice structure. Meanwhile, the diameter of the single cell strut decreases, and the stress it can bear decreases, which leads to a decline in the compressive mechanical property of the lattice structure. However, the number of struts increases with the increase of interlacing cells, which makes the stress distribution of the lattice structure more uniform. The cyclic compression results indicate that with increasing interlacing-cell number, the proportion of the hyperelastic recoverable strain increases, and the residual strain in the cyclic compression test decreases. For the lattice structure with a chiral arrangement of single cells, the manufacturability, compressive mechanical properties, and hyperelasticity are comparable to those with a normal arrangement.

The surface/subsurface of both machined workpieces and used diamond tools were characterized, and the machining characteristics, such as chip formation and cutting forces, were also investigated. It was found that microcracks occurred easily in the feed-in/cut-in area of the dimples, which is caused by a large friction-induced tensile stress due to a large thrust force. The dimples located on the secondary cleavage directions &lt;10−10&gt; (S-dimples) were easy to produce crack-free surfaces, while the dimples located on the primary cleavage directions &lt;−12−10&gt; (P-dimples) were very prone to cause cracks on surfaces, even though the chips were formed in a </span>ductile mode<span>.
