Abrasive flow machining is a process to deburr, polish and radius difficult-to-reach surfaces. In this process small quantities of work material are removed by flowing semi-solid, abrasive dispersed putty (for sealing glass) or dough under pressure through or across work piece material. Number of cycles, Extrusion pressure, flow volume, grit size, media, and work piece geometry are the prior machining parameters that improve the surface finish properties. Recently majority of researchers are focusing to create hybrid processes by merging abrasive flow machining process with other non-conventional processes. By implementation of hybrid processes materials with complicated shapes which are difficult to machine have been possible. It finds application in modular head of hip joint, extrusion die, aerospace, pharmaceutical and automobile industry. This paper presents the past research on different developments in hybrid AFM processes, different rheological properties of abrasive flow machining medium, findings of different process parameters and also review the finishing results of various materials such as brass, aluminum and mild steel. This paper also gives directions to the future aspects of abrasive flow machining by including organic abrasive laden media which will be beneficial to protect our environment.
