Swirling Abrasive Fluidized Bed Machining (SA-FBM) is a novel variant of Fluidized Bed Machining (FBM). This research focuses on the experiments performed on copper specimens using silicon carbide abrasive particles to investigate the influence of operating parameters such as grain size, superficial velocity, and machining time on metal removal rate, transformation of surface texture, and the surface finish. The study concludes that the surface modification is faster with SA-FBM compared with conventional FBM; the initial roughness conditions of the workpiece have no effect on the maximum possible surface finish; moreover, for faster metal removal, higher superficial velocity, and for better surface finish, fine abrasive grains are preferred.

“…Sharper abrasives result in higher metal removal rate due to the concurrent action of multiple cutting edges [1,13]. As the abrasive grain size goes on increasing, the indentations on the metal surface go deeper due to the change in kinetic energy [3,14].…”

“…In addition, the data scattering were considerably reduced after the third machining step, and thus emphasizing the capability of FBM to induce a very uniform sutface morphology on the processed substrates. This result agrees well with the findings of Barletta when FBM was applied to either ductile and soft or hard and tough metal or ceramic substrates [17].…”

“…5{d)). This result agrees very well with what was found by Barletta in a previous investigation on the time dependency of ductile polymeric coatings during scratch tests with hard and sharp indenters at different sliding speeds [17]. In that analysis, they found that ductile polymeric coatings became stiffer with increasing sliding speed during constant load scratch tests, leading to a corresponding ductile-glassy transition, and that the resulting residual scratch patterns became correspondingly narrower and shallower.…”

“…As the machining proceeded, a slower improvement in surface finishing occurred, and an asymptotic finishing condition was identified. The same behavior was exhibited by ductile metal substrates, such as aluminum and brass, when machined in a bubbling bed with alumina as the abrading particles [17] or when machined by abrasive fiow machining [1]. Even in these cases, the machining processes were very effective in the initial stage of the process.…”

In this paper, the mechanisms of material removal during the fluidized bed machining (FBM) of polymeric substrates are analyzed. Cylindrical components composed of polyvinyl chloride (PVC) were exposed to the impact of abrasives while rotating at high speed within a fluidization column. The interaction between the Al2O3 abrasive media and the PVC surfaces was studied to identify the effect of the main process parameters, such as the machining time, the abrasive mesh size, and the rotational speed. The change in the surface morphology as a function of the process parameters was evaluated using field emission gun-scanning electron microscopy (FEG-SEM) and contact gauge profilometry. An improvement in the finishing of the processed surfaces was achieved, and the related mechanisms were identified. The roles of the impact speed and the contact conditions between the abrading particles and the substrate were also investigated
