Review of surface roughness and material removing rate on abrasive flow machining process

Abstract

Every day, advancements in manufacturing technology research and innovation yield a highly finished surface with lower labour and machining costs. The conventional materials that were frequently employed in the chemical, automotive, and aerospace industries have been replaced by materials like ceramics, metal matrix composites, polymers, and super alloys. The AFM technology is capable of maintaining precision, reliability, and adaptability across adverse range of applications. Internal parts, through holes, intersecting holes, and freeform surfaces that are challenging to finish with other conventional finishing techniques can all be polished and deburred with AFM. The current study aims to determine the process variables that have a major impact on the change in surface roughness of the inner, outer, and side surfaces as well as the amount of material removal. These parameters include abrasive mesh size, abrasive concentration in media, and the number of passes. A review of published technical articles on the AFM process is attempted in this article, and the studies are divided into four categories: experimental setups, abrasive media, modelling and optimisation, and applications of the AFM process. The review article provides fresh directions for future investigation. Page layout
