Repairing of airfoil components using hybrid manufacturing strategies requires both rapid digitization and non-rigid registration methods. In this study, several profile digitization strategies are investigated to determine effects on accuracy of the final non-rigid registration of the component geometry and the impact on the quality measures pertaining to parent material blendlines. These profile digitization strategies include approaches based on curvature-based segmentation, G1 and G2 continuity, and local control of maximum profile deviation. From these results, it is seen that by locally controlling maximum profile deviation, it is possible to achieve acceptable profile tolerance limits while limiting the number of points required for profile digitization.
