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.
Claims13
A method for forming the contour of at least a portion of an edge of an airfoil having a plurality of airfoil sections, which comprises:
- disposing a tool having the shape of the edge adjacent the edge so that the tool will engage the edge when reciprocated;
- engaging the edge of the airfoil with the edge on the tool to position the tool on the airfoil;
- engaging a spanwisely extending reference surface on the airfoil to further position the tool at each airfoil section with respect to the airfoil surface by permitting movement of the tool at that airfoil section with respect to the edge of the airfoil;
- applying a force to the tool;
- and,
- removing material by repeatedly moving the tool relative to the edge in the spanwise direction while positioning the tool during travel at each airfoil section with respect to the spanwisely extending surface and with respect to the airfoil edge in response to engaging the airfoil edge and engaging the reference surface on the airfoil.
