In order to reduce development and production costs, a continuous flow of knowledge and information between product development and process planning of machined components is being developed as part of the DFG-funded project WiToPro. Ontologies are to be used to structure the information flow and the interface between the two domains.

Goal and task description – The aim of this master's thesis is to develop an understanding of product development activities in the CAD-CAM process chain. The knowledge gained is to be structured in the form of an ontology in order to lay the foundation for partially automated knowledge-based tolerance allocation in product development. The individual steps to achieve the goal are:

• Familiarization with the topics of ontologies, product development and the CAD-CAM process chain

• Development of a methodology for creating the product ontology including requirements and boundaries

• Creation, verification and validation of the ontology
