Abrasive flow machining (AFM), also known as extrude honing, is a method of smoothing and polishing internal surfaces and producing controlled radii. A one-way or two-way flow of an abrasive media is extruded through a work piece, smoothing and finishing rough surfaces. In one-way systems, we flow the media through the work piece, then it exits from the part. In two-way flow, two vertically opposed cylinders flow the abrasive media back and forth. In the paper, the various types of abrasive laden polymer media, their work piece applications as well as the compatibility with the abrasives used is explained. The properties of the polymer used in AFM are compared and the best combination of polymer, abrasive and hydrocarbon oil is selected. Apart from polymer properties, the media flow equations, abrasive wear and forces is also studied.
