The selection of abrasive material is one of the critical factors in AJM. Common abrasives include aluminum oxide, silicon carbide, and garnet, each with its own properties affecting cutting efficiency. The hardness, shape, and size of the abrasive particles play pivotal roles in the material removal rate (MRR) and surface finish. Hard materials often result in higher MRR, while the shape influences the way particles interact with the workpiece surface.
