US Patent:

61062049, Aug 22, 2000

Filed:

Sep 3, 1998

Appl. No.:

9/146302

Inventors:

Richard James Dansereau - Cromwell CT
Edward Charles Toohey - Hebron CT
John Sebastian Interlandi - Newington CT
Steve Joseph Mezei - San Diego CA

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

B23C 100

US Classification:

409183

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.

Abstract:

A method for forming at least a portion of the edge 12, 14 of an airfoil 10 using a cutting tool 164 is disclosed. Various details of this method are developed which enable incremental removal of material by repetitively moving the tool with respect to the edge while positioning the tool with respect to a spanwisely extending airfoil R. sub. 5, on the airfoil.
