Ultrasonic vibration assisted machining (UVAM) is an attractive solution for upgrading the machinability of SiCp/Al composites. However, the impact of different amplitudes on the surface/subsurface formation mechanism has not been systematically investigated. In this study, the evolution of cutting force, surface quality, subsurface damage (SSD) and microstructural deformation under different ultrasonic vibration amplitudes was thoroughly investigated by a series of machining and testing experiments. The reduction proportion of the cutting force is enhanced with the growth of ultrasonic vibration amplitude, and the decrease in cutting force primarily derives from the Al matrix. The variation of surface roughness is governed by the alteration of SiC particle removal pattern under ultrasonic vibration, and a reasonable ultrasonic vibration amplitude facilitates particle fragments rather than fracture. Additionally, the occurrence of SSD depends on the collective effect of the cutting force and the high frequency vibration of the tool. It is worth emphasizing that the small cutting force may not imply the expected surface/subsurface improvement. The minimal surface roughness and SSD depth are achieved when the ultrasonic vibration amplitude is 5 μm. Finally, the residual tensile stress occurs in SiC particles and the grain refinement of Al matrix is observed. This study contributes to the rational selection of ultrasonic vibration amplitude in manufacturing so as to enhance the potential applications of SiCp/Al composites.</div></div>","PeriodicalId":54589,"journal":{"name":"Precision Engineering-Journal of the International Societies for Precision Engineering and Nanotechnology","volume":"95 ","pages":"Pages 526-537"},"PeriodicalIF":3.5,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144138737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, during the compensation grinding process, geometric errors can induce deviations in the grinding trajectory, thereby adversely affecting the corrective outcomes for surface accuracy. Consequently, this study introduces an optimization method for aspheric grinding surface accuracy that integrates sensitive geometric error identification with in-situ compensation processing techniques, aiming to mitigate the impacts of geometric errors on compensation processing performance. Initially, a volumetric error model of the grinding machine was established based on multibody system theory, and the evolution pattern of the peak-to-valley (PV) values under the influence of geometric errors for various types of optical components was simulated and analyzed. Subsequently, using actual inverse kinematics, analytical expressions for the computer numerical control (CNC) code for compensating geometric errors across various motion axes of the grinder were derived. Thereafter, a geometric error-surface accuracy model (GE-SAM) was constructed to elucidate the interrelationship between geometric errors and surface accuracy. Based on this model, a global sensitivity analysis was employed to identify critical geometric error terms affecting the surface accuracy of aspheric grinding, which further streamlined the analytical expressions for the compensation CNC code. Finally, the efficacy of the proposed method was substantiated through experimental validation. The experimental results demonstrated that the surface accuracy optimization strategy proposed in this paper is more effective than the traditional in-situ compensation processing method.</div></div>","PeriodicalId":54589,"journal":{"name":"Precision Engineering-Journal of the International Societies for Precision Engineering and Nanotechnology","volume":"95 ","pages":"Pages 566-577"},"PeriodicalIF":3.5,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144169565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To guarantee the stability of the transposition system under heavy loads and large floating volumes, an air cushion structure supported by aerostatic pressure with slender holes is proposed. Based on Computational Fluid Dynamics (CFD), the effects of traditional orifices, slender orifices, cylindrical cavity, and square cavity throttling on the air cushion pressure distribution and flow field characteristics were analyzed, determining the superior performance of the slender orifice structure. Furthermore, the influence of structural factors, including throttling hole diameter, number and length-diameter ratio, on air cushion performance and floating displacement is discussed. The findings indicate that, at a film thickness of 34 μm, the slender hole exhibits a bearing capacity 7.28 times higher than that of the small hole, accompanied by a stiffness that is 3.28 times increased. Moreover, for slender holes, a positive correlation is observed between the load capacity and both the diameter and the number of throttling holes, while stiffness is negatively correlated with these parameters. The length-diameter ratio has a negligible influence on both load capacity and stiffness. Building on the above findings, a ceramic-supported air cushion with an orifice diameter of 1 mm was fabricated, and floating displacement measurements were conducted. Under a load of approximately 1000 kg, the air cushion lift exceeded 20 μm, thereby validating its supporting performance. The maximum error compared to the calculated results was less than 5.96 %.
