Toothed members, such as curvic couplings, are commonly found in gas turbine engines as they provide connection between engine parts and permit highly precise centering and stacking of engine parts. Given the tight tolerances required for aerospace applications, such toothed members have to be machined with great accuracy in order to ensure proper functioning in the engine. Therefore, machine tool operators are typically required to make several manual interventions during the machining process in order to ensure that parameters (e.g. concentricity, perpendicularity, addendum, pitch plane height, contact pattern) associated with a freshly machined toothed member are within required specifications. In particular, as part of the conventional manufacturing process, an operator is typically required to use a master gauge, depth micrometer, and height gauge at various stages of the machining process to ensure that the dimensions of the freshly machined part are within tolerance. Given the complexity of the manufacturing process, a substantial amount of manual measurement and setup operations is required, which proves time consuming and costly.
There is therefore a need for improved systems and methods for manufacturing parts, such as toothed members, that are subject to tight tolerances.
