“…D2 pre-machined hardened tool steel as a work piece and reported that AFM is capable of removing an EDM damaged surface and significantly improving the surface roughness as well as of inducing high compressive residual stresses onto the machined surface. Bähre et al [9] developed a setup to measure the axial forces under applied media pressure during the AFM of AISI 4140 steel. They presented the influence of media pressure on the surface quality and form tolerance.…”

Abrasive flow machining (AFM) is a manufacturing technique that uses the flow of a pressurized abrasive media to remove workpiece material. In comparison with other polishing technique, AFM is very efficient, suitable for the finishing of complex inner surfaces. In this paper, the effect of workpiece hardness on the AFM process has been investigated. An experimental study was carried out on AISI D2 tool steel hardened to 31, 45 and 55 HRC. The specimens were cut by using wire electro discharge machining (WEDM) and then finished with AFM. The results show that the white layer formed during WEDM is successfully removed by AFM in a few cycles. Although the surface quality is improved by AFM for all hardness groups, the results show that harder materials have more surface improvement than the softer ones.

“…Bell mouthing resulting due to unguided media flow at the exit worsens the roundness (form) factor from entry to exit along the passage length. The diameter of the hole varies unevenly along the length with increasing number of passes revealing uneven material removal [8]. The surface parameters found to improve rapidly during early phases of honing owing to removal of dominant surface asperities, followed by progressive improvement due to crest flattening with deterioration of surfaces in later stages.…”

The surface requirements of engineering components vary widely depending on where the surface is being applied for. Fabrication of surfaces having desired characterises on materials possessing high hardness is the need of the hour to effectively overcome the contemporary application challenges. The surface generation of these difficult to cut material carrying intricate and unable to reach geometries could not be met by existing conventional finishing processes. So, several non-conventional finishing techniques were developed to meet the ever-growing requirements, among them, Extrusion Honing or Abrasive Flow Machining that works on flexible media carrying abrasive particles acting as tool can successfully fine finish the surface. In the present study, the effect of process parameters of one-way extrusion honing on the surface characterises of Titanium Grade 2 is undertaken. The surface roughness is studied using stylus type surface measuring instrument and surface texture of the specimen before and after the process is analysed using SEM images. The results show a significant enhancement in surface finish using EH/AFM process and the process found quite capable in removing the surface irregularities and producing surface with enhanced overall surface integrity.

The abrasive flow finishing processes are advanced finishing techniques widely used as finishing solutions in high-end industries like aerospace, automobile, tool and die, and prosthetic. Abrasive flow finishing processes are mainly used for polishing, deburring, removal of cast layers, radiusing and finishing intricate shapes by flowing abrasive laden viscoelastic carrier over the surfaces to be finished. Although abrasive flow finishing have a wide range of applications and could be used in every shop floor as a finishing solution, their usage is limited owing to high initial and running costs associated with them. This article attempts to present a novel classification of abrasive flow finishing processes based upon the use of different energy and tooling, and highlights the critical research outcomes in each category. The physical abrasive flow finishing modeling, developments in abrasive flow finishing processes, and their hybridization with the other manufacturing processes are discussed. Finally, the future research challenges including the development of low-cost alternative media, development of tooling and fixture, and environmental issues in the area of abrasive flow finishing are highlighted.
