We have a subassembly with a ball and socket joint. We don’t have a reliable way to measure the internal spherical diameter of the socket other than bluing it and checking with the corresponding ball. This method is open to interpretation, as well as doesn’t give you an actual number to the size or roundness. These parts are held to really tight tolerances too (+/- .00025 inch) which makes it even more difficult. Anyone know any better methods or inspection tools?
