SAE ARP6911 PDF

This SAE Aerospace Recommended Practice will serve as a practical resource that offers guidance to both the machine operator and process engineer for isolating the source(s) of non-repeatability in measured unbalance data. The content of this standard addresses:

• Machine capability to achieve the specified unbalance tolerances and repeat within those tolerances.
• Tooling capability to repeat within the specified unbalance tolerances.
• Rotor characteristics that may preclude repeating within the required unbalance tolerances.
