Abstract

A tool includes a flexible section; a head that extends form the flexible section; and an exciter within the head. A method of additively manufacturing a component including burrowing a tool into a conglomerated powder within an internal passage of an additively manufactured component, the tool vibrating in a manner to facilitate removal of the conglomerated powder.

First claim

1 . A tool, comprising:
a flexible section with at least one groove within an outer diameter of the flexible section; a head that extends from the flexible section; and an exciter within the head, the tool vibrating in a manner to facilitate removal of a conglomerated powder.

2 . The tool as recited in claim 1 , further comprising an abrasive material on the head.

3 . The tool as recited in claim 1 , wherein the exciter is at least one of an ultrasonic, piezo, hydraulic, and pneumatic exciter.

4 . (canceled)

5 . The tool as recited in claim 1 , wherein the at least one groove spirals around the outer diameter of the flexible section.

6 . The tool as recited in claim 1 , further comprises a lubrication passage through the flexible section to excrete a lubricant from the head.

7 . The tool as recited in claim 1 , wherein the flexible section is rotatable.

8 - 18 . (canceled)
