- Points of contact
- Use the technical expertise of the Structural Fabrication Branch.
- Include the Production Planner and Fabrication Technician as part of your team early in the process.
- Enter your Work Order into the database or submit one in writing. Call the Structural Fabrication Branch.
- All flight hardware delivered to fabrication area must have a parts control tag or a serviceable tag with that item.
- Deliver prints and sketches as soon as possible.
- Submit as much information about the task as possible at the start.
- Specify reasonable deadlines.
- Use commonly available materials and fasteners whenever possible. Check with Structural Fabrication Branch Production Planner early on for availability.
- Understand the impact of very tight tolerances and multiple chemical surface finishes. Both of these drastically increase cost and time requirements.
Tips for Manufacturability
- Re-evaluate tolerances and inside corner radius and be as generous as possible.
- Review notes and specifications to insure that they apply.
- Specify readily available materials and hardware whenever possible.
- Have drawings checked and signed by someone other than the designer who is intimately familiar with ANSI Y14.5, "Dimensioning and Tolerancing."
- Use Military Specifications, Federal Standards and National Aerospace Standards whenever possible. AVOID proprietary specifications.
- Check reproductions for quality and readability.
- Avoid multiple finishes (Anodize, iridite electroplates) on a component. Masking and multiple processes are slow, expensive and risky.
