Abstract: For products having internal inaccessible cavities or recesses, general finishing processes like lapping, honing etc. are used but they suffer from disadvantage of low quality of surface finish and that too with high equipment cost. Therefore need arises for an alternate process which has the capability of nano-level finishing. Abrasive Flow machining (AFM) is such kind of fine finishing technique for such products. This method has a unique property of simultaneous improvement in material removal and surface finish. It employs an abrasives laden semi-solid media, which acts as a self-deforming cutting tool and can finish the complex cavities under a hydraulic pressure. During the finishing of components by using Abrasive Flow Machining, there is a very important role of pressure distribution, velocity and temperature distribution at different points in Abrasive Flow Machining. The work piece hardness, abrasive size, abrasive hardness, Extrusion pressure and properties of carrier media are the important process parameters that affect the performance of AFM. Abrasive flow Machining has a limitation of low material removal. So to reduce this limitation, a variable magnetic field has been introduced in the path of the abrasive particle. So, my main aim in this report work is to study the different types of hybrids are possible in this AFM process and to choose one of them to cause more material removal and better surface smoothness.
