Few topics in dimensional metrology will inflame the passions of a metrologist, but the subject of this column--thread gages vs. thread comparators--is one of them. In the gaging industry, when asked to choose the best method to qualify a screw thread, few ride the fence. And those who try to stay neutral become targets for both sides.
The subject is fraught with misconceptions, misunderstandings, horror stories, politics and junk metrology. The fervor can border on such a level of fanaticism that common sense is completely lost.
