  • Apparatus for forming the edge of an airfoil
    Patent number: 6106204
    Abstract: An apparatus 28 for forming at least a portion of the edge 12,14 of airfoil 10 using a tool assembly 68 is disclosed. The tool assembly has a tool 164 with a cutting face 202 having a shape which is like the shape of the finished edge of the airfoil. Various construction details of the apparatus are developed which enable the tool to incrementally remove material while accommodating wave-like variations in the airfoil edge. In one embodiment, the apparatus has a probe assembly 166 attached to the tool which is moveable with respect to a reference surface R.sub.s on the airfoil to guide the tool.
