S-136 (STAVAX ESR) as a mould material has been extensively used in the optical lens manufacturing industry. In this study, the aspheric surface made of S-136 fixed by a six-degree of freedom (DOF) manipulator was polished using magnetic compound fluid (MCF) slurry. The effects of experimental parameters included rotational speed of workpiece and MCF slurry composition on surface roughness Ra and shape retention were investigated. The results demonstrated that the cutting marks on the initial surface reduced obviously under the given experimental parameters. Therefore, the smoothest surface with Ra 20 nm was obtained with MCF3 containing micro-sized Fe3O4 particles with lower saturation magnetisation at nw = 1,000 rpm. The material removes uniformly during the polishing process and the Pearson correlation coefficient (Pcc) of the aspheric surface was kept above 0.994. The MCF slurry polishing was demonstrated as a potential method to smooth the S-136 aspheric surface.

Ball end magnetorheological finishing (BEMRF) process provides nano level of surface finish for materials which are magnetic as well as non-magnetic in nature. The available literature on this process has been vastly limited to establishing its finishing capabilities on materials of different nature. This research work deals with theoretical investigations into surface roughness reduction in BEMRF process, performance of machining parameters during long time periods and providing their representation in mathematical terms. Starting with the mechanism of abrasive wear in BEMRF process, this work advances to find out prolonged effect of abrasive rubbing on a ferromagnetic workpiece surface. The study finds out a phenomenon termed as transient roughness reduction in which the material removal by abrasive wear in BEMRF process is diminished with time and a particular combination of machining parameters and fluid composition reduce roughness only up to a critical value, beyond which no further reduction is achieved. A mathematical model is developed to depict this transient roughness reduction phenomenon, the model is then experimentally verified and the close proximity of the experimental results with the theoretical ones validates the model and the transient roughness reduction phenomenon in BEMRF process.

The magnetic abrasive flow finishing (MAFF) process has been developed and investigated as an advanced fine finishing process. It is used for a surface finish (SF) of the straight and complex intricate profile using the ferromagnetic nature of abrasive media. This article presents an experimental investigation on the newly developed MAFF attachment, which was mounted on a shaper machine. A custom design workpiece fixture was used in MAFF attachment for the finishing of a straight hollow cylinder shape workpiece, which can easily modify based on workpiece shapes. A curved workpiece seat was prepared and fasting with two brass plates by nut and bolts arrangement. Taguchi design of experiment approach applied for experimentation on aluminium 6061-T6 workpiece material by MAFF setup. The main process parameters considered for experimentation are magnetic flux density (MFD), number of cycles, abrasive concentration, and piston speed while responses are material removal (MR) and surface finish (SF). The results found after finishing by MAFF were also compared with the AFF. It was identified that remarkable enhancements observed in MAFF responses. The finished surfaces were also observed by scanning electron microscope (SEM) and X-ray diffraction (X-RD).

Pre-stressed hardening grinding (PSHG) can control the residual stress after grinding, and its surface layer has impacting hardening (IH) effect besides the well-known quenching hardening effect due to the impact of abrasive grain. In order to study its IH, the paper established the IH model of PSHG using ANSYS simulation method considering the main factors of grinding impacting. The IH characteristic and mechanism was revealed. The IH effect mainly concentrates on the surface layer and reduces rapidly along the direction of depth. It increases with the increase of pre-stress and the grinding depth due to their comprehensive promotion of dislocation, dynamic recovery of crystal grain and motion characteristic of the iron atom. The IH experiment of PSHG was carried on and the simulation model was verified by and large. The model can reveal the IH characteristic accurately.
