Seal Slot Inspection Process

In this example, a complex seal slot feature on a nickel alloy engine component was inspected using the RSH-M10 Robotic 3D Metrology System. The automated system performed full-area scanning of the slot and surrounding features. The process included automatic alignment to reference datums and data merging from multiple scan paths to ensure full coverage. Once the scan was complete, automated feature extraction routines were used to isolate and evaluate slot width, depth, and flatness. The dimensional characteristics were analyzed in reference to a defined datum scheme to ensure full compliance with engineering specifications.
