Prototype of flexible ball step gauge artifact – News Briefs – National Institute of Standards and Technology, Air Force develop standardized gauge for coordinate measuring machines – Brief Article
As part of the program to maintain quality control on coordinate measuring machines (CMMs) for the Air Force, NIST completed a prototype ball step gauge artifact. The gauge is the first of a series to be used throughout the Air Force as a new calibration procedure for CMMs. The use of a ball step gauge will allow CMMs to be calibrated quickly and easily according to an established protocol. The system is capable of positioning to eight azimuthal positions, at five different vertical incliniations. Each position is repeatable, so that CMM calibration can occur with a minimal of operator interaction. The data obtained from the calibrated gauge will be used to establish part-specific measurement uncertainty using the method of simulation by constraints developed at NIST.
