Precedent-Oriented Geometrical Modeling of the Parts and Assembly Units of an Aircraft Pipeline

The paper deals with constructional an technological preparation to manufacturing the pipeline units of aircraft with the use of welding. Designing of such preparation is oriented on reusable geometrical modeling of parts and their assemblies that keep relations with a master geometry of a corresponding aircraft. For integrating the models, it is applied the specialized ontology. Proposed means provide the necessary accuracy positioning of parts in conditions oriented on their welding by a robot.
