Abstract: Abrasive flow machining (AFM) process is a non-traditional finishing process, that enables finishing of complex inaccessible internal surfaces by rubbing abrasive grains mixed in visco-elastic carrier medium over the surface that is to be finished. In this work, mechanism of material removal (MR) during finishing of internal surfaces using unidirectional AFM process is modelled and simulated numerically. The numerical model is validated by performing experiments on unidirectional AFM setup. Design of experiments is used to investigate the influence of extrusion pressure, finishing time and viscosity of the flow medium on the performance measure parameter. It is found that MR rate depends strongly on extrusion pressure, finishing time and viscosity of medium.
