Abstract:
A system for automatically inspecting the true position of cooling holes manufactured in hot section turbine blades and vanes. The system includes a computer controlled rotary tilt table for correctly positioning the blade or vane having the cooling holes, and computer controlled, a coordinate measuring machine for positioning a video camera in the X, Y, Z directions so that it can look straight into the selected cooling hole of the blade or vane. An image analyzer receives the image from the video camera, calculates the centroid of the image, and the host computer calculates and reports deviation between the actual or true position of the cooling hole and data relating to the correct position of the same. A touch probe is also provided with the coordinate measuring machine to verify the correct position of the blade or vane prior to imaging.
