For example, for CNC milling, is it advisable on the PFMEA to: (A) generalize about 4-5 failure modes for CNC milling (e.g. fixture error, load error, operator error, machine error, program error, tool wear/breakage) as common modes across all print features or (B) list the generic modes in (A) but also discretely list those KPC/KCC features as they map from the flow diagram? Presumably this is a way to exhibit enhanced detection methods (error-proofing, etc) for KPC/KCC features. Our question about this arose because we were trying to assign occurrence/detection scores to the generic failure modes. Like most manufacturers, we only do first article inspection for some print features, some we periodically SPC, some we 100% limit gage and some are error-proofed into subsequent operations; each feature type gets a different detection score, so how do you reflect this on the PFMEA without itemizing every feature? Our thinking is that listing the KPC/KCC features is a good compromise. Thoughts?
