O.K......I will flog a dead mule. I worked as a machinist for 20 years before moving into quality. Anyone who thinks that thread milling produces a thread void of irregularity is wrong. Yes.....wrong. You will still have raised edges , frayed edges, etc. Bottom line: there is no clear cut way to check thread location on a CMM, period. You can be approximate. Never exact. Which is what we strive for.
