The goal of this new Aerospace Information Report is to supplement the content of AS6327™ and provide a reference document for the new Aerospace Standard. This new Aerospace Information Report will serve as a practical resource that offers guidance to the machine operator and Process Engineer for isolating the source(s) of non-repeatability in measured unbalance data. The content will include: • 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.
AS6327™ - Methods and Criteria for the Balancing of Gas Turbine Rigid Rotors establishes requirements to ensure the integrity of balancing processes. For the sake of brevity, AS6327™ may not include investigative test protocols necessary to establish an effective process to isolate source(s) of process non-repeatability. The objective of this document is to address that need. This Aerospace Information Report will be useful to Machine Operators and Process Engineers.
