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.
Claims19
A tool for machining chamfers comprising:
- 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 defined through the tool body to provide access to the workpiece for a router;
- and
- a router attachment proximate the router port, wherein the router attachment 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, wherein each of the first and second references includes a bolt, spaced apart from one another along a longitudinal axis of the workpiece, wherein the bolts are configured to mount the tool body to a workpiece with the router attachment positioned for correct placement of the chamfer in the workpiece, wherein the router attachment is obliquely angled relative to the longitudinal axis to position a router to form a chamfer with an acute angle.

(canceled)
A method of machining a chamfer comprising:
- mounting a tool body to a workpiece using at least two references to positively position the tool body relative to the workpiece;
- mounting a router to the tool body, with a router bit extending through a router port defined through the tool body;
- and
- sliding the router along the tool body with the router forming a chamfer in the workpiece, wherein mounting the tool body to the workpiece includes bolting the tool body to a first bore in the workpiece thereof using a first bolt, and bolting the tool body to a second bore in the workpiece using a second bolt, wherein the first and second bolts are spaced apart along a longitudinal axis of the rotor blade.
