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.

Apparatus for forming the edge of an airfoil

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.

Method for forming the edge of an airfoil

The present invention relates to a tool for accurately controlling the location, volume and containment of an abrasive grit material during a plating operation wherein the grit material and a matrix metal are deposited onto a tip portion of at least one workpiece. The tool of the present invention has an inner component with slots for receiving the workpieces to be coated. The tool also has an outer components having a plurality of through slots for permitting a plating solution to flow therethrough and into a space defined by the inner and outer components. The tool further has a slot defined by portions of the inner and outer component for introducing the abrasive grit material into the space. A screen is provided over the slots in the outer component. The screen helps maintain the abrasive grit material within the space while permitting plating solution to flow into the space. The tool of the present invention further has a trough for collecting unused grit material. A method for forming a coating on a tip portion of a workpiece or workpieces using the tool of the present invention is also disclosed.
