Swirling Abrasive Fluidized Bed Machining: Effect of Process Parameters on Machining Performance

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.
