Abrasive Flow Machining (AFM) is a non-traditional finishing method used for precision deburring, edge contouring, surface improvement and the removal of abusive machining and thermal recast layers. A firm-bodied abrasive laden compound is flowed at pressures of 75–500 psi (5–35 bar) across selective features of a fixtured workpiece. Gas turbine components benefited by this method include: axial and centrifugal rotors, stators, turbine blades, compressor and turbine disks, shafts, seals and other rotating parts. AFM process principles are explained and specific applications are reviewed.
