Balancing Systems ? Isolating Repeatability Issues in Challenging Balancing Applications
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.
Rationale: 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.
