Abrasive medium plays an important role in the application of abrasive flow machining (AFM), a process that finishes complex internal and external geometries. A new abrasive medium needs to be fabricated due to a lack of literature on it. In this work, a new abrasive medium was fabricated by using styrene butadiene rubber (SBR) as carrier and DF-101S was used to study its characterization. Results showed that new abrasive medium with good fluidity and temperature stability was obtained. Processing experiments have also been carried out by using new abrasive medium and MLLD60, and ZYGO was used to study the surface characteristics of the work-piece. Experimental results indicate that the new abrasive medium is applicable to AFM process.

Surface Improvement

The abrasive flow machining (AFM) is used to deburr, radius, polish and remove recast layer of components in a wide range of applications. Material is removed from the workpiece by a flowing semisolid mass across the surface to be finished. In this study a medium for AFM has been developed from the various viscoelastic carriers and has been contrasted through experimental investigation. The viscoelastic media are selected on the basis of existing media through the studies of thermogravimetric analysis and are characterized by mechanical, as well as rheological, properties with the help of a universal testing machine and a rheometer. The performance of the medium is evaluated through the finishing criteria on a two-way AFM setup. The investigation reveals that the styrene butadiene rubber (SBR) medium gives a good improvement in surface finish. The surface improvement through SBR media is 88%. It is also found that the strain, temperature, shear rate, time of applied constant stress, cyclic loading, etc. have an impact on the mechanical and rheological properties of the newly developed medium, which are ultimately governed by the performance of the medium in the target applications.
