Benefits of technology
The solution provides a cost-effective and reliable method to secure gas turbine engine blades during manufacturing, ensuring accurate positioning and minimizing distortion, thus reducing manufacturing time and costs while maintaining precision.
Problems solved by technology
Specifically, when the component is a gas turbine engine blade, accurate manufacturing of the blade may be one of the most significant factors affecting an overall cost of fabrication of the gas turbine engine, as well as subsequent modifications, repairs, and inspections of the blade.
However, using such a matrix does not always produce accurate results that are reliable or easily repeatable.
In addition, using a matrix may require multiple fixtures, machines, and / or processes.
Furthermore, a matrix may decrease how rigidly the blade is held during manufacturing, which may result in a slower manufacturing time of the blade.

Abstract
A method enables a component to be secured within a tool for manufacture. The tool includes a fixture, a component locator, and a clamping member. The method includes fixedly coupling the component locator to the fixture, coupling the clamping member to the fixture, locating the component within the tool using the component locator such that the component is positioned for manufacture with respect to the fixture, securing the component within the tool between the component locator and the clamping member such that the component locator, the clamping member, and the component are fixedly secured in position for manufacture with respect to the fixture, and retaining the component in position with respect to the fixture using the component locator and the clamping member.
Description
BACKGROUND OF THE INVENTION [0001] This invention relates generally to manufacturing techniques, and more specifically to methods and apparatus for securing components for manufacture. [0002] Accurate manufacturing of a component may be a significant factor in determining a manufacturing time of the component. Specifically, when the component is a gas turbine engine blade, accurate manufacturing of the blade may be one of the most significant factors affecting an overall cost of fabrication of the gas turbine engine, as well as subsequent modifications, repairs, and inspections of the blade. For example, gas turbine engine blades include a tip shroud that typically requires an accurately machined radius along the tip and center section of the blade. The radius is established using a system of datums referenced about the profile of the blade. More specifically, to establish the datums, the blades must be rigidly held during manufacturing, such that the tip shroud is maintained in pos...
