Laboratory demonstration of high sensitivity forging inspection utilizing an alternative technique for curved entry surface inspection. Factory demonstration of high sensitivity forging inspection including digital C-scan data acquisition performed on 30 separate forgings. Report of laboratory and factory evaluations including sensitivity data for use by the Inspection Systems Capability Working Group and cost comparisons for the different inspection approaches. Metrics: Demonstration of 1/128” (#½) FBH sensitivity inspection with digital C-scan data acquisition and SNR-based reject criterion for representative titanium forgings using zoned inspection approach with inspection speed comparable to current inspections.
