  • Masking method for edge profile finishing
    Patent number: 8308526
    Abstract: A mask for performing high speed media finishing on airfoils includes a thicker portion and a thinner portion. The thicker portion is spaced further from an edge that will become a leading edge in the final airfoil than the thinner portion. The media is redirected by the thicker portion toward the edge where the finishing is to occur.
    Type: Grant
