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.
The reasons for developing a hybrid machining process is to make use of combined or mutually enhanced advantages and to avoid or reduce some of the adverse effects the constituent processes produce when they are individually applied.
In almost all non-conventional machining processes such as electric discharge machining, electrochemical machining, laser beam machining, etc., low material removal rate is considered a general problem and attempts are continuing to develop techniques to overcome it. The present paper reports the preliminary results of an on-going research project being conducted with the aim of exploring techniques for improving material removal (MR) in AFM. One such technique studied uses a magnetic field around the work piece. Magnetic fields have been successfully exploited in the past, such as machining force in magnetic abrasive finishing (MAF), used for micro machining and finishing of components, particularly circular tubes. The process under investigation is the combination of AFM and MAF, and is given the name

Magneto Abrasive Flow Machining (MAFM).


Following process parameters were hypothesised to influence
the performance of MAFM:
1. Flow rate (volume) of the medium,
2. Magnetic flux density,
3. Number of cycles,
4. Extrusion pressure,
5. Viscosity of the medium,
6. Grain size and concentration of the abrasive,
7. Work piece material,
8. Flow volume of the medium, and
9. Reduction ratio.


The volume of abrasive particles is carried by the abrasive fluid through the work piece. Abrasives are impinged on the work piece with a specified pressure which is provided by the piston and cylinder arrangement or with the help of an intensifier pump. The pressure
energy of the fluid is converted into kinetic energy of the fluid in order to get high velocity.
When a strong magnetic field is applied around the work piece, the flowing abrasive particles (which must essentially be magnetic in
nature) experience a sideways pull that causes a deflection in their path of movement to get them to impingeon to the work surface with a small angle, thereby resulting in microchipping of the surface. The magnetic field is also expected to affect the abrasive distribution pattern at the machining surface of the work piece. The particles that otherwise would have passed without striking the surface now change their path and take an active part in the abrasion process, thus causing an enhancement in material removal. It is to be mentioned here that although the mechanical pull generated by the magnetic field is small, it is sufficient to deflect the abrasive
particles, which are already moving at considerable speed. Therefore it appears that, by virtue of the application of the magnetic field, more abrasive particles strike the surface. Simultaneously, some of them impinge on the surface at small angles, resulting in an increased amount of cutting wear and thereby giving rise to an overall enhancement of material removal rate.
