A system and method for readily generating radial clearance data for a radial clearance between locations on at least two parts in a rotating machine includes rendering an image of a cross section view of at least a portion of the machine on a display. The locations on the two parts are identified on the rendered cross section, and a radial stack path between the identified locations is automatically determined. The radial clearance between the identified locations when the machine is not operating is determined, based at least in part on the determined radial stack path. Data generated by a deflection analysis model of the machine are used to determine radial deflections of the identified locations during machine operation at one or more machine operating conditions. Data representative of the radial clearance between the identified locations during the machine operation at the one or more machine operating conditions are generated.

A hoop stress relief mechanism is disclosed for use on a rotary body to relieve stress caused by both thermal and centrifugal forces. The mechanism may consist of a J-shaped slot cut from the outer rim of the rotary body a distance inwardly toward the axis of rotation, the slot having a curve in its inward end that curves back towards the outer rim. The J-shaped slot may extend through the rotary body to join its two faces. The J-shaped slot may be fabricated by an electric discharge wire machine. The electric discharge wire machine may make multiple passes in order to smooth the bottom surface of the curved slot portion.
