Abstract

Free form nonrigid parts are the inseparable part of today’s automotive and aerospace industries. These parts have different shapes in free state due to dimensional and geometric variations, gravity and residual strains. For the geometric inspection of such compliant parts, special inspection fixtures, in combination with coordinate measuring systems (CMM) and/or optical data acquisition devices (scanners) are used. A general procedure to eliminate the use of inspection fixtures was developed by our previous work. Here we apply a new method for robustifying the generalized numerical inspection fixture (GNIF). We filter out points causing incoherent geodesic distances. We demonstrate that our approach has several significant advantages one of which is the ability to handle parts with missing range data. The other advantage of presented method is the capacity to inspect the parts with large deformations.
