Holes that require a specific type of fit, either clearance, interference, or transition, also require a higher degree of accuracy. Noncontact hole inspection devices provide this, as well as an ability to measure fragile parts and high volumes of parts. These more sophisticated variable hole inspection devices include coordinate measuring machines, measuring microscopes, optical comparators, borescopes, laser systems, and air gages. Job specifications, part dimensions, and feature size all determine which hole inspection device to use on holes requiring a certain fit. Choosing a tool without a high degree of accuracy could result in an out-of-tolerance hole passing inspection. After taking this class, users will be able to describe advanced methods for inspecting hole dimensions and geometric features in a lab setting.
