Summary: The study focused on the impact of wall-slip velocity of abrasive medium on the workpiece material removal rate in abrasive flow machining process. The coupling effect of wall shear stress and workpiece surface roughness on wall-slip characteristics was explored. A novel method based on fluid mechanics and AFM experiments was proposed to determine wall-slip velocity, and power-law mathematical models were derived to describe the relationship between wall-slip velocity, wall shear stress, and workpiece surface roughness. The models were validated through verification tests, and the results showed that the proposed method and mathematical models improved the prediction accuracy of MRR in AFM process.

Summary: The development of fine surface finish without defects remains a challenge for the current industry, especially in the precision manufacturing of components. Traditional finishing methods struggle to polish difficult-to-reach surfaces, internal surfaces, and complex geometries. Magnetically Assisted Abrasive flow machining (MAAFM) is a non-conventional technique that effectively addresses these challenges and finds application across various industries.

Summary: This research investigated the impact of temperature on surface roughness and material removal rate using a one-way abrasive flow machining with SiC, Al2O3, and B2O3 particles as abrasive particles. The findings showed that media containing Al2O3 particles had higher surface roughness, and material removal rate decreased as temperature decreased.

Summary: Abrasive flow machining (AFM) is increasingly used for finishing closed complicated flow channels machined by electrical discharge machining (EDM) due to its high machining accessibility, surface integrity, and efficiency. This study focuses on the finishing nonuniformity, which is the uniformity of material removal distribution, in EDM machined complicated flow channels by AFM. The theoretical analysis, experimental results, and flow simulations show that finishing nonuniformity is influenced by the non-uniform flow field of the abrasive medium and is affected by the EDM and AFM surface roughness. Based on these findings, guidelines for parameter optimization in the combined EDM + AFM process are discussed.

Summary: This study proposed a soft-contact model and defined soft-contact parameters to characterize soft-contact characteristics in abrasive flow machining (AFM). The study investigated the effect of medium pressure and particle diameter on soft-contact parameters, and found that the scratch depth of the abrasive particles increased with increasing particle diameter and medium pressure. The study also revealed that the abrasive particles were deeply wrapped by the abrasive medium and that the covering inclination angle increased with increasing medium pressure and particle diameter.

Summary: Thermal additive centrifugal abrasive flow machining (TACAFM) is a new hybrid method that addresses the low material removal efficiency of abrasive flow machining caused by spark formation and the centrifugal force generated by the electrode. A novel triangular electrode was proposed to improve the efficiency of the TACAFM process, which was validated through simulation, experimentation, and artificial neural network modeling. The experimental results showed a small average cumulative percentage absolute error for material removal and surface finish improvement, confirming the effectiveness of the proposed electrode.

Summary: This study investigated the stiffness of two different lattice structures fabricated from PLA-wood material using FDM. The results showed that lattice beams were more sensitive to shear deformation, and the infill density had a similar effect on the effective stiffness. However, different lattice structures exhibited different stiffness differences at different infill densities. The stiffness results of PLA-wood samples were scattered, which was attributed to the inherent defects in the lattice elements of the material.
