System and method for collecting measurement data of shaped cooling holes of CMC components

Abstract:

A measurement system and methods for collecting measurement data for features of ceramic matrix composite (CMC) components are provided. In one aspect, the system and methods provided herein can be utilized to collect measurement data for a cooling hole of a CMC component. The measurement system includes a sensor system that includes a chromatic confocal sensor and a charged coupled device. The chromatic confocal sensor emits stacked cones of light each having an associated wavelength. The stacked cones are moved over a target surface of the CMC component and the charged coupled device measures one or more characteristics associated with the reflected light. The characteristics are then used by a computing device to generate a measurement data file representative of the geometric profile of the cooling hole. A rotary table system can position the CMC component to present the cooling hole at different orientations.
