The last years have shown that the tooling industry has experienced a fundamental change of its boundary conditions. Besides the influence of new technology trends this fundamental change is mainly caused by two game changing trends namely the globalization and derivatization. Globalization led to a global competition with new providers from low wage countries in Eastern Europe and Asia. The derivation trend results in increasingly individual product architecture which enhances the number of variants and thus results in a variety of different components. Therefore tooling companies are forced to produce more tools at consequently lower tool budgets. In order to stay successful in global competition tooling companies are required to provide technical superior products at competitive prices. These effects result in complex challenges for value creation of tooling companies in high wage countries. Tool manufacturing is responsible for the major share of value creation. Therefore tooling companies have to create their capital employed in tool manufacturing economically and produce with a high efficiency. The milling technology is characterized as the most important manufacturing technology in tooling. Due to further developments in milling technology e.g. high speed cutting or five axes manufacturing, the importance will further increase in the future. On the other hand these developments likewise increase the technological complexity because of the growing number of different milling variants. Moreover, continuously increasing demands of materials and component geometry resul t in a variety of different milling tools. Milling tools are a significant cost driver in tool manufacturing. Thus, the optimization of milling tool use by enhancing tool life and reuse of milling tools is becoming more important for tooling companies. In this thesis a model for life cycle oriented milling tool management in small batch production is developed. An analysis of existing approaches concerning milling tool management and life cycle management will be performed. In the model action fields will be deducted and elaborated as well as further research needs are identified. The specification of the action fields is supported by methodical approaches to standardize and optimize milling tool management with the consideration of milling tool life cycle.
