Preferential Media for Abrasive Flow Machining

Journal of Manufacturing Science and Engineering, 2009
The abrasive flow machining (AFM) is used to deburr, radius, polish and remove recast layer of components in a wide range of applications. Material is removed from the workpiece by a flowing semisolid mass across the surface to be finished. In this study a medium for AFM has been developed from the various viscoelastic carriers and has been contrasted ...

Rheological characterisation of abrasive media and finishing behaviours in abrasive flow machining

The International Journal of Advanced Manufacturing Technology, 2020
Flow field simulation of abrasive media in a constrained passage in abrasive flow machining (AFM) plays a decisive role in optimising process parameters and designing the core of a fixture. Based on the experimental rheological characterisation of various types of abrasive media, a model of flow field simulation of abrasive media was constructed by ...

Study on the Characteristics of New Abrasive Medium for Abrasive Flow Machining

Advanced Materials Research, 2013
Abrasive medium plays an important role in the application of abrasive flow machining (AFM), a process that finishes complex internal and external geometries. A new abrasive medium needs to be fabricated due to a lack of literature on it. In this work, a new abrasive medium was fabricated by using styrene butadiene rubber (SBR) as carrier and DF-101S ...

Analysis of Flowing Characteristics of Abrasive Flow Machining in Slit

Key Engineering Materials, 2011
Based on the equations of motion and rheological theory of abrasive flow in the slit, effect between wall slip and grinding has been analyzed and grinding flow model of abrasive flow has been built in this paper. Wall pressure, wall shear stress, wall slip and the grinding force equation of abrasive flow were derived using the model. What is important,

Experimental determination of viscosity of abrasive flow machining media

International Journal of Manufacturing Technology and Management, 2005
Abrasive flow machining (AFM) is a non-traditional process used to de-burr, radius, polish and remove recast layers of the components in a wide range of applications. The material removal in abrasive flow machining takes place by flowing the media, mixed with abrasives, across the surface to be machined.

Force behaviour in abrasive flow machining

International Journal of Materials and Product Technology, 2002
Hydroforming processing of sheet metal parts provides a number of advantages over conventional processes including reduction in the number of parts, and reduction in the tooling and material costs. As a result, the technology has drawn increasing attention from many industries. However, there is still little experience available of both the process and

Abrasive flow machining: a case study

Journal of Materials Processing Technology, 1991
Abstract Abrasive flow machining finishes surfaces and edges by forcing a flowable abrasive media through or across the workpiece. Abrasion occurs only where the media flow is restricted; other areas remain unaffected. It can process many selected passages on a workpiece simultaneously, reaching even typically inaccessible areas. Several or dozens of
