Abstract Based on the feature approach a new method for selection and configuration of tools is developed for turning, drilling and milling operations. This method takes into account mainly technology factors besides the workpiece geometry and the process strategy. Selection rules are developed and transformed into real tool parameters according to the new standardization aspects on tool characteristics. The planning functions are integrated into an object oriented engineering database. In this context the required resource models and the STEP (Standard for the exchange of Product Model Data) based information models are explained. The potentials of the implementation are discussed in regard to rationalization targets.
