Abrasive Flow Finishing (AFF) is an advanced finishing process where the viscoelastic laden medium acts as a continuously deforming grinding tool to finish intricate features and complex components with relative ease. The description of the process and mechanism of material removal is discussed in sections 2 and 3, respectively. 2.
Grinding fluids can also help to keep the wheel surface clean and provide corrosion protection for newly machined surfaces. Lubrication by grinding fluids reduces the friction and wear associated with the grinding process, thereby allowing for more efficient operation with less consumption of the abrasive, as will be seen in Chapter 11.

Abrasive suspension flow machining (ASFM) is an advanced finishing method that uses an abrasive suspension slurry for grinding and chamfering as well as the finishing of inaccessible components. This study examines the effect of back pressure on the grinding characteristics of an abrasive suspension flow during the grinding of slender holes. A numerical model was developed to simulate the ...
The Abrasive Flow Machining (AFM) process is ideal for polishing and deburring, especially for complex internal shapes and targeted surface challenges.. Whether your component finishing operation is as routine as surface polishing or burr removal or as complex as final shaping of slots, breakthroughs and drilled hole openings, our Abrasive Flow Machine (AFM) process will meet your needs.
Abrasive Flow Machining Process. AFM utilizes two opposed cylinders that force abrasive media through workpiece and tooling passages. The abrasion operates only within the extrusion area where the flow is restricted. The machining action of AFM is comparable to grinding or lapping, where abrasive media gently and uniformly smooths material ...
This research established a mathematical model of the useful grinding fluid flow rate of a rough grinding wheel. The abrasive distribution matrix of the grinding wheel surface topography was programmed on the MATLAB software platform to obtain the grinding wheel porosity φ at different particle sizes. The grinding fluid flow field was simulated and studied by using the volume of fluid ...

A relatively new non-traditional process called Abrasive-Flow Machining (AFM) is being used to deburr, polish, radius, remove recast layers, or produce compressive residual stresses in a wide range of applications. Material is removed from the workpiece by the flowing of an abrasive-laden viscoelastic compound across the surface to be machined.

• Grinding is a chip removal process that uses an individual abrasive grain as the cutting tool. • The differences between grinding and a single point cutting tool is: –The abrasive grains have irregular shapes and are spaced randomly along the periphery of the wheel. –The average rake angle of the grain is typically -60 degrees.
Abrasive suspension flow machining (ASFM) is a new grinding technology that came forth in recent years [].This method was originally developed for aerospace applications and later introduced to diesel engine applications, including micro-hole …
Overall, many similarities were found between grinding and abrasive-flow machining. This suggests that AFM is a very capable finishing process, and that its area of application should be expanded. AB - Deburring and surface finishing methods represent a critical and expensive segment of the overall manufacturing process.
To move grinding wheel speeds into the ultra-high speed grinding (UHSG) regime (above 40,000 fpm or 200 m/sec), the wheel core must be made of metal, and the abrasive is likely to be plated. Such wheels can run at nearsonic speeds (66,000 fpm or 335 m/sec) without the fear of bursting.
The schematic diagram of ECG system is shown in Fig. 6.3. In ECG system, rotating conductive metal bonded abrasive grinding wheel acts as cathode and workpiece acts as anode in electrolytic cell. The wheel rotates at a surface speed of 20–35 m/s. Bonding materials are copper, brass, bronze, nickel or copper impregnated resin.
