“…The results indicated that surface roughness of the cylindrical passageway notably decreased to 0.28 μm Ra from an initial value of 1.8 μm Ra after 5 working cycles [6]. Based on experimental study, it was observed that abrasive mesh size and percentage of abrasive concentration in media are the most significant parameters for material removal and improvement in surface roughness.…”

Due to the fact that abrasive media can deform flexibly in abrasive flow machining (AFM) making this method easily to polish the complex holes and the curved surface of the hard machining shapes. Although abrasive media dominate the polishing behavior in AFM process, the mechanism of the abrasive media are not easy to understand because of the high viscous gels, therefore, many finishing works need lots of time to design AFM process. Power laws of the abrasive gels is studied here to evaluate the non-Newtonian flow of abrasive gels in complex holes polishing firstly, at the mean time different abrasive gels are utilized to finish the complex holes to follow the results by non-Newtonian flow calculation. Moreover, traditional AFM has difficulty to achieve a uniform roughness of radial distribution in the complex holes polishing because of the non-uniform abrasive forces. So a helical passageway is proposed to create a multiple motion of abrasive medium and to obtain the even surface of the complex holes in AFM process.

“…It also revealed that the fluidity and stickiness nature of the self-modulating abrasive medium could be automatically adjusted, and used to finish tiny micro channels. Wang et al [65] carried out experiments and removed recast layer of a complex hole by AFM process. Jain et al [66] applied Finite Element Method (FEM) to study AFF of complex geometry.…”

Freeform surfaces are being used in a multiplicity of applications in different kinds of industries related to Bio-medical (Bio-implants), micro channels in micro fluidics, automotives, turbine blades, impellers of artificial heart pumps, automobiles etc. Different parts in these industries need nano-level surface finish as their functional inevitability. It is very difficult and challenging to achieve high level of surface finish, especially on the components having freeform (or sculptured) surfaces, complex shapes, and 3-D features. Surface finish is a significant factor, which affects life and functionality of a product. Many traditional and advanced finishing processes have been developed for finishing of freeform/sculptured surfaces but still it has not been possible to achieve uniform nano level surface finish specially in case of freeform surfaces. To overcome the limitations of the existing nanofinishing processes, researchers are developing new processes for uniform nanofinishing of freeform surfaces. In this article, an attempt has been made to review different nanofinishing processes employed for freeform surfaces useful in different types of applications. In addition, experimental work, theoretical analysis and existing challenges of the finishing processes have been identified to fill the research gap.

“…Uhlmann et al 82 developed a process model using modern simulation techniques by determining the basic principles of AFM on ceramic materials and created relationship between flow processes, surface development, and edge rounding. Wang et al 83 described that at a constant pressure, the velocities, strain rates, and shear forces of the AFM media acting on the finishing profile can be evaluated. In analyzing the influence of AFM process variables on MRR and surface finish quality, Jain et al 84 used artificial neural network (ANN) and multivariable regression analysis (MVRA) technique in AFM process.…”

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.
