<p>A two step operation passage forming process includes steps to minize tolerance build up between the operations. The method includes a step of determining a spatial error between the coordinate systems of the two operations. In a particular embodiment, the step of determining the spatial error includes forming an indexing hole in a template at a particular location using the first operation, aligning the apparatus of the second operation with the indexing hole, and measuring the spatial error between the actual position of the indexing hole and a translated position. The determined spatial error may then be used as an offset in the second operation to account for tolerance differences between the two operations.</p> |
