If the bores are geometrically modeled as cylinders, this leads to the necessity of determining the minimal Euclidean distances between cylinders and testing them against the corresponding margins. In this paper a very fast and reliable algorithm for the distance computation between cylinders is introduced, which has been developed due to the run-time requirements of the problem at hand.enReihe CI; 259-08004report
