Abstract:
A method for forming a modular unit of a rotary machine disposed about an axis A, the modular unit of the rotary machine having a stator assembly which includes a case and vane assembly having a case, coolable stator vane clusters disposed about the interior of the case, and a circumferentially extending seal member supported by the stator vane clusters, the seal member having an as ground finished contour after machining, comprising the steps of:machining the seal member to its finished contour by removing particles of material from the seal element;masking the case and vane assembly to block particles from entering the vanes during machining; and, after machining the seal member;cleaning the stator assembly without disassembling every vane cluster from the case; and,assembling the modular unit of the rotary machine that contains the stator assembly;wherein not disassembling a stator vane cluster for cleaning the stator vane cluster avoids disrupting the as ground contour of the seal member associated with that stator vane cluster and avoids the need to reassemble the stator vane cluster to the case prior to finally assembling the modular unit of the machine.
