Shell Drill Cell Assembly #1270
For this project, although simple in concept, used every facet of our facility. The end goal was to drill two seven-millimeter holes through an ear that would eventually receive a plastic pin through it and hold the shell to the rest of the mirror assembly. A custom left and right-hand fixture for each shell was necessary and incorporated Poke-Yoke concepts to eliminate incorrect shell loading and wrong fixture use. The fixtures themselves were 3d machined nests that used vacuum to keep the shells nested while an autodrill on each end of the work station placed the hole in it’s proper location. Once the operator has the shell loaded, they place their fingers in the finger swipes to verify their hands are clear of the operation areas, vacuum kicks on, drill one fires and then drill two fires and the vacuum was released.
