Study of Surface Finishing using Abrasive Flow Machining

Magneto abrasive flow machining (MAFM) is a new technique in machining. The orbital flow machining process has been recently claimed to be another improvement over AFM, which performs three-dimensional machining of complex components. These processes can be classified as hybrid machining processes (HMP)—a recent concept in the advancement of non-conventional machining.

Abrasive flow machining: a case study - Extrude Hone

Abrasive flow machining (AFM) is a nontraditional machining process that was developed in the USA in the 1960s. AFM can be described as pressurized media passing through the surfaces to reach the desired surface quality. There are mainly two types of abrasive flow machines according to flow of media: one-way and two-way.

(PDF) Abrasive flow machining (AFM): An Overview

The abrasive flow machining (AFM) is a new finishing operation that involves abrasive particles as the tool to remove work material. AFM is broadly known as ―no-tool‖ precision finishing operation and the carrier media containing abrasive particles is called as ―self-deformable stone‖. In AFM, a semi-solid polymer-based media

Experimentation of Abrasive flow machining

3.3 Machining - Abrasive Flow machining (AFM) is a non-traditional machining process that may be used to deburr, radius, polish, remove recast layers, and to produce compressive residual stresses. It is a process of polishing and smoothening internal surfaces and thereby producing controlled radii. The abrasive media is flown across the
