ABSTRACT: Accurate determination of the distance between fastener holes and part edges is critical to ensure structural integrity in military aircraft. These measurements are particularly important as part flanges are reduced and tolerances are tightened to save weight and increase performance. Current measurement methods rely on manual calipers and are extremely time consuming, labor intensive, and prone to operator-induced errors. Creare proposes to develop a handheld inspection tool capable of measuring hole diameter and associated hole-to-edge distance. Our system is designed to be very easy to use and fast enough to provide immediate feedback to the operator. During Phase II, we will develop a prototype system and evaluate system performance in conjunction with our Manufacturing Partner to evaluate accuracy, suitability for use in the manufacturing environment, and ease-of-use. BENEFIT: The handheld inspection tool developed on this project is expected to have broad application in aircraft inspection for measurement of part geometry, fastener placement, and gap thickness. Creare is also actively pursuing commercial applications in industrial manufacturing and other sectors.
