The measurement, or metrology, of physical objects is a fundamental requirement for industrial progress. Dimensional measurement capability lies at the heart of ones ability to produce objects within the required technical specifications. Dimensional metrology systems are presently dominated by touch-probe technologies, which are mature and reliable. Due to the intricate geometries required in certain fields of manufacturing, these contract probes cannot be physically brought in proximity to the measurement surface, or lack sufficient lateral resolution to satisfactorily determine the surface profile, which can occur in the measurement of gears, splines and thread. Optical probes are viable candidates to supplement the contact probes, since light can be focused to less than one micron (40 microinches), no contact occurs that can mar highly finished surfaces, and no probes must be replaced due to wear. However, optical probes typically excel only on one type of surface: mirror-like or diffuse, and the optical stylus itself is oftentimes not as compact as its contact probe counterpart. Apeiron, Inc. has pioneered the use of optical non-contact sensors to measure machined parts, especially threads, gears and splines. The Oak Ridge Metrology Center at Oak Ridge Y-12 Plant are world-class experts in dimensional metrology. The goal of this CRADA is to tap the expertise in Oak Ridge to evaluate Apeiron`s platform, and to suggest new or novel methods of optical surface sensing, if appropriate.
