Research trends in abrasive flow machining: A systematic review

Abstract

Abstract The components used in aerospace, automotive, and biomedical industries are made up of modern materials like titanium alloys, ceramics, composites etc. However, the complexity in the shape of such materials limits the use of conventional processes for their finishing. Abrasive flow machining (AFM) is one such alternative to finish these components. In this review study, a systematic methodology has been used for a data-supported review of AFM. The methodology includes a structured literature search, bibliometric analysis, and text mapping. The development of AFM variants, parametric analysis, abrasive media development, modeling of responses of AFM, and application-based studies are identified as major fields of investigations in AFM. The study of AFM variants includes the development of better versions of AFM using external assistances to improve process performance. The effect of input parameters on process responses is studied for parametric analysis. The development of abrasive media using different base polymers and their use have also been explained. The modeling of process responses of AFM is explicated using mathematical equations. Besides this, the behaviour of abrasive media has been analyzed using mathematical and simulation studies. The details about the use of AFM in finishing of biomedical components, automotive parts, gears, additively manufactured parts, turbine blades, and micro geometries have been provided to understand the practical applications of AFM in the recent past.
