Case Study: RUAG achieves precise in-machine inspection for jet-engine fan rings with Hexagon m&h probing systems

RUAG - Customer Case Study

RUAG Aerospace, a Swiss manufacturer of complex components for the aerospace and defense industries, faced a challenge in producing thin-walled, large-diameter jet engine fan rings with extremely high accuracy. Their main problem was the inability to measure these critical parts on a coordinate measuring machine (CMM) to adjust for run-out. Hexagon provided a solution using its m&h 3D Form Inspect software and modular touch-probes to perform in-process inspection directly on the machine tool.

The solution from Hexagon involved implementing m&h touch-probes with infrared transmission and the 3D Form Inspect software on RUAG's machining centers. The software managed multiple probes, automatically generated NC programs with calibration, and compensated for thermal and axis deviations. This allowed for immediate measurement and decision-making during machining. The results were highly accurate, differing from CMM results by only microns, and were absolutely repeatable. This provided RUAG with production certainty, prevented costly scrap, enabled immediate rework, and paid for itself in a short time.
