In this paper, abrasive flow machining (AFM), which is effective for improving the precision on property of the surface and shape of a small hole of a Ti–6Al–4V alloy fabricated by electric discharge machining, is described. AFM is a finishing process used on internal shapes which are difficult to finish by other machining methods. It can perform surface polishing removing a small quantity of material by flowing fluid abrasive medium through or across a small gap of workpiece, under a constant extrusion pressure. The shape of a small hole fabricated by EDM is not straight, i.e., the diameter of the entrance is larger than that of the exit, and the machined surface is not smooth, either. The experimental results show that using AFM polishing as finishing process can significantly improve the quality of the machined surface and of the shape of the small hole of the Ti–6Al–4V alloy. It is also shown that the quantity of removal material and the hole precision are remarkably affected by the concentration of abrasive, extrusion pressure, number of cycles and working time.
