Project Milestones:
- Developted a process for deep hole drilling and boring to maintain alignment of bushing seats. Max tolerance for concentricity was +/- .0002”. This was obtained by using three stage machining process that allow consistant repeatability over the entire run of 55 pieces.
- Applied drilling process to 8 other hinges in a family of parts.
