Abstract
A tool for machining chamfers includes a tool body defining a first reference and a second reference configured for proper positioning of the tool body on a workpiece. A router port is defined through the tool body to provide access to the workpiece for a router. A router attachment proximate the router port is configured to position a router mounted to the router attachment for machining a chamfer in the workpiece with reference to the first and second references.
Claims9
A method of machining a chamfer comprising:
- mounting a tool body having a router port comprising an opening defined by a substantially continuous edge to a root end of a rotor blade using at least two references to positively position the tool body in a fixed position relative to the root end of the rotor blade;
- mounting a router to the tool body, with a router bit extending through the router port defined through the tool body;
- and
- sliding the router between two rails arranged adjacent to the opening along the tool body relative to the root end of the rotor blade and tool body with the router forming a chamfer in the root end of the rotor blade, wherein mounting the tool body to the root end of the rotor blade includes bolting the tool body to a first bore in the root end of the rotor blade thereof using a first bolt, and bolting the tool body to a second bore in the root end of the rotor blade using a second bolt, wherein the first and second bolts are spaced apart along a longitudinal axis of the root end of the rotor blade.
