Fatigue Performance in Abrasive Flow Machining
Applied Mechanics and Materials, 2014Surface finish and Manufacturing process has a prominent role in the fatigue life of a machine component. Fatigue strength of a material generally increases with the surface finish. But the super finishing process like electro polishing reduces the fatigue strength of the material.

Simulation of the abrasive flow machining process
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2013AbstractDuring the last decade the abrasive flow machining process became an accepted technique to smooth and to round inner edges in badly contactable regions of complex geometries, e.g. grooves in rails of common rail systems. The process is based on the flow of a highly viscous silicone oil which is charged by abrasive particles.

Preferential Media for Abrasive Flow Machining
Journal of Manufacturing Science and Engineering, 2009The 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 ...

Study on the Characteristics of New Abrasive Medium for Abrasive Flow Machining
Advanced Materials Research, 2013Abrasive 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 ...

Abrasive flow machining: a case study
Journal of Materials Processing Technology, 1991Abstract 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
