In many manufacturing processes, it is crucial to improve surface finish, especially when producing components with tight tolerances and high aesthetic quality, for specific functional performance. Manual assisted polishing methods are limited in their ability to achieve accuracy, reputability, and reach inaccessible areas of a complex part. An effective finishing method can be standardized through the automation process for improving surface roughness. Irrespective of complex geometries surface finish is achievable through abrasive flow finishing (AFF). The current work experimentally investigates on improving the surface roughness of the cylindrical bush at the location of bore and face through AFF. The cast iron materials of bush elements are finished at the required surfaces using innovative AFFM fixture design. The simultaneous finishing of multiple numbers of dies are evaluated by considering various process parameters of the abrasive flow finishing process. The comparative study of surface roughness before and after the abrasive flow finishing has been analyzed.
