“…There were many developments over the last few decades in the cost-effective and quality-assured manufacturing of precisely finished components for a variety of industrial applications. 1,2 There are a number of finishing processes involving the use of abrasives, for example, abrasive flow machining, 3–5 magneto-rheological fluid-based machining 6,7 and magnetic abrasive finishing (MAF). 8 In MAF, the finishing forces are primarily controlled by the magnetic field produced by a permanent magnet or an electromagnet.…”

A new finishing technique called ultrasonic-assisted magnetic abrasive finishing integrates ultrasonic vibration with magnetic abrasive finishing process for finishing of workpiece surface more efficiently as compared to magnetic abrasive finishing in the nanometer range. During finishing, two types of forces are generated in ultrasonic-assisted magnetic abrasive finishing, namely, a normal force (indentation force) and a tangential force (cutting force) that produces a torque. The finishing forces have direct control on the rate of change of surface roughness and material removal rate of the workpiece surface. This article deals with the theoretical modeling of the normal force and the finishing torque based on the process physics. In this work, finite element simulations of the electromagnet were performed to calculate a magnetic flux density in the working zone; they were also used to evaluate the normal force on the workpiece surface. The theory of friction for the abrasion of metals was applied together with the effect of ultrasonic vibration to calculate the finishing torque. The developed model predicts the normal force and finishing torque in ultrasonic-assisted magnetic abrasive finishing as functions of the supply voltage, working gap and concentration of abrasive particles in a flexible magnetic abrasive brush. A comparison of theoretical and experimental results is performed to validate the proposed model.

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.

“…The processing effect of the abrasive flow is directly related to the hardness of the abrasive particle. 27 Since the titanium alloy has a high surface hardness, silicon carbide was selected as the abrasive particles. D is the abrasive particle size, φ is the concentration of abrasive particle, t is the processing time, Ra is the measured value of the surface roughness, and Ra ′ is the predictive value.…”

In order to study the machining mechanism and process of abrasive flow machining for the titanium alloy artificial joint surface, the abrasive flow machining experimental platform and the curved surface profiling flow channel were established for the machining. The influence of various process parameters (abrasive particle size, abrasive particle concentration, and processing time) and interaction factors on surface roughness and surface micro-topography of the workpiece was quantitatively evaluated through response surface analysis, and a surface roughness prediction model was established. The experimental results show that coverage constraint abrasive flow machining can significantly improve the surface quality of the titanium alloy artificial joint surface, thereby improving the wear resistance and service life of the artificial joint. Using abrasive flow machining with a smaller abrasive particle size and a larger concentration can obtain smaller surface roughness. Under the experimental conditions, the influence of process parameters on the surface roughness is in descending order of processing time, abrasive particle concentration, and abrasive particle size. And the interaction of processing time and abrasive particle size is more effective during processing. The research results can provide the basis for optimizing the flow channel structure for the abrasive flow machining of the titanium alloy artificial joint surface and have a certain guiding significance on the process optimization.
