Developments in abrasive flow machining: a review on experimental investigations using abrasive flow machining variants and media

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2012
The abrasive flow machining (AFM) technique uses a self-deforming tool, an abrasive laden media that is passed back and forth in the passage geometry of the hollow workpiece with the assistance of two hydraulically operated cylinders placed opposite to each other.

Autonomous Control of Abrasive Flow Precision Machining

Advanced Materials Research, 2011
Autonomous nodes distribution, including their relations, real time quality and network communication in abrasive flow precision machining (AFPM) was studied. Autonomous nodes are arranged according to their function. Control program of motor speed is copied into liquid level nodes, pressure nodes, temperature nodes, flux nodes and input/output nodes ...

Development of magneto abrasive flow machining process

International Journal of Machine Tools and Manufacture, 2002
Abrasive flow machining (AFM) is a relatively new process among non-conventional machining processes. Low material removal rate happens to be one serious limitation of almost all such processes. Limited efforts have hitherto been directed towards improving the efficiency of these processes so as to achieve higher material removal rates by applying ...

Finite element simulation of abrasive flow machining

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2003
The abrasive flow machining (AFM) process can be applied to an impressive range of finishing operations, providing uniform, repeatable and predictive results. It offers higher productivity, automation, flexibility and ability to control the intensity and location of machining.

Simulation of the abrasive flow machining process

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2013
AbstractDuring 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.

Gas Turbine Applications of Abrasive Flow Machining

Volume 5: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education; General, 1989
Abrasive Flow Machining (AFM) is a non-traditional finishing method used for precision deburring, edge contouring, surface improvement and the removal of abusive machining and thermal recast layers. A firm-bodied abrasive laden compound is flowed at pressures of 75–500 psi (5–35 bar) across selective features of a fixtured workpiece.

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 ...

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

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,
