Orbital hole match drilling

摘要

A method of forming a hole 550 in a work-piece 560 having first 566 and second 568 layers of material includes providing the first layer of material with a through-hole 564 positioned adjacent the second layer of material. An orbital drill 510 is secured to the first layer of material to position a cutting tool 526 of the drill within the through-hole. During operation, when the cutting tool is used to cut a hole in the second layer of material, the alignment keeps the orbital drill stationary. The method may be used to manufacture a multi-layer aircraft component.
