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.

The scope of this SAE Aerospace Information Report includes practical applications, theory, process management, audit and control recommendations, recommended validation intervals, verification and validation, file setup parameters, additional considerations, and process documentation.

This document recommends general designs, tolerances, limits of application and suitable tooling, fixtures and accessories for mounting and driving jet engine rotors on horizontal and vertical balancing machines.

This document recommends general designs, tolerances, limits of application and suitable tooling, fixtures and accessories for mounting and driving jet engine rotors on horizontal and vertical balancing machines.

This document establishes general design criteria, tolerances, and limits of application for tooling, fixtures and accessories for mounting and driving gas turbine engine rotors on horizontal and vertical balancing machines. For your own safety, while using balancing tooling, regard the safety instructions of the individual supplier.

This SAE Aerospace Recommended Practice (ARP) specifies the requirements of balancing machines that make them suitable for the subject class of work. It was developed for soft-bearing balancing machines but may also be used for hard-bearing machines until ARP4050 is issued for that type of machine.

The specific performance requirements preceding each test in Section 9 have been written to define certain characteristics of the machine. Conformance with the tests constitutes what is considered minimum proof that the machine will meet these requirements. The test procedures will not prove conformance with all requirements over the full range of all variables, neither will they measure nor define the exact reasons for nonconformance in a given test. Failure of a machine to conform may be due to shortcomings in specific components or to more general reasons such as lack of ruggedness, improper leveling or anchoring to the floor, etc.

This document specifies those requirements of a balancing machine which make it suitable for the subject class of work. It will specify: (a) Sensitivity, (b) Accuracy of indications of amount and location of unbalance, (c) Ability to separate the Dynamic Unbalance into two planes and to separate Force and Couple Unbalance, (d) Machine capacity relating to weight and physical dimensions of the rotors which can be balanced, (e) Balancing speed of rotation, (f) Standard balancing machine drive adapter flange dimensions, (g) Standard shroud mounting pads, (h) Power requirements.
