“…The characteristic feature of MAM is that it employs very small machining pressure and is easily controllable with the help of input current to the electromagnet. Magnetically assisted abrasive flow machining, which is the combination of AFM and magnetic abrasive finishing (MAF), has been shown to give better results than obtained from individual AFM or MAF [24]. Literature survey indicates that though AFM has excellent characteristics as regards generation of super finish on inaccessible areas of workpiece surface, limited efforts have hitherto been directed towards improving the process efficiency of AFM.…”

Abrasive flow machining (AFM) is a nonconventional finishing process that deburrs and polishes by forcing an abrasive laden media across the workpiece surface. The process embraces a wide range of applications from critical aerospace and medical components to highproduction volumes of parts. One serious limitation of this process is its low productivity in terms of rate of improvement in surface roughness. Limited efforts have hitherto been directed towards enhancing the productivity of this process with regard to better quality of workpiece surface. This paper discusses improved fixturing as a technique for productivity enhancement in terms of surface roughness (R a ). A rotating centrifugal-force-generating (CFG) rod is used inside the cylindrical workpiece which provides the centrifugal force to the abrasive particles normal to the axis of workpiece. The effect of the key parameters on the performance of process has been studied. The results shows that for a given improvement in R a value, the processing time can be reduced by as much as 70-80%. It is seen that the significant process parameters are revolutions per minute of CFG rod, extrusion pressure and abrasive mesh size.
