“…DeGroote, et al (7) further developed this model through the inclusion of the near surface mechanical properties, abrasive size and concentration, glass chemical durability, and glass average single bond strength and quantified the effect of each term on the MRR by performing various experiments. Schinhaerl, et al (8), (9) performed a mathematical modeling study that takes into account process parameters, such as the wheel speed, the magnetic field strength, and the fluid flow rate, to predict the shape and size of the influence function that contains the information about the material removal characteristic of the polishing tool on high-quality optical lenses, and they experimentally verified the effectiveness of their model. In the wheel-type MR finishing process, the MR fluid is attached to a rotating wheel-shaped permanent magnet and directly imposes the shear stress at the workpiece surface, thus removing the materials (Seok, et al (11)).…”
