    摘要： A method (60) for inspecting an internal cavity (44) in a part (12) is provided. The method (60) includes inserting (62) a probe (14) into the internal cavity (44). The method (60) also includes controlling (62) movement of the probe (14) using a defined scan path to scan the probe (14) over a region of interest in the internal cavity (44). The method (60) also includes applying (64) multiple multifrequency excitation signals to the probe (14) to generate a number of multifrequency response signals. The multifrequency excitation signals are applied (68) at multiple positions within the internal cavity (14). The method (60) further includes performing a multifrequency phase analysis on the multifrequency response signals to inspect the internal cavity (14).

    摘要： A multi-focus probe (100) that includes a motor (250) communicatively coupled with a lead screw (254) and configured to turn the lead screw (254) about a lengthwise axis of the lead screw (254), wherein the lead screw (254) includes a length having threads. The probe (100) also includes a lead-screw nut (256) positioned about the lead screw (254) such that the lead-screw nut (256) engages the threads and such that the lead-screw nut (256) and the lead screw (254) can move relative to one another via the threads, a transducer (104) configured to move vertically with the lead screw (254), and an enclosure (106) surrounding the transducer (104), wherein the enclosure (106) includes a probe face (118) configured to hold fluid and engage a wave emission target such that waves from the transducer (104) can enter the target. Further, the probe (100) includes a capture feature (268) capable of engaging the lead-screw nut (256) such that the lead-screw nut (256) is vertically fixed relative to the probe face (118) and such that the lead screw (254) moves away from the probe face (118) when rotating within the lead-screw nut (256) in a first direction and moves toward the probe face (118) when rotating within the lead-screw nut (256) in a second direction opposite to the first direction while the lead-screw nut (256) is engaged by the capture feature (268).

    摘要： An apparatus and method are provided for servicing a dynamoelectric machine. The apparatus includes a tool delivery mechanism adapted for delivering a tool (560) to a desired location in the dynamoelectric machine, and a tool support fixture (700) adapted to be secured onto the body of the dynamoelectric machine, where the tool support fixture (700) can be used for supporting and adjusting the tool delivery mechanism. A sleeve mechanism (710) is attached to the tool support fixture (700), and the sleeve mechanism (710) is disposed around a portion of the tool delivery mechanism. The apparatus is adapted to service the component of the dynamoelectric machine in-situ.
