Feature Technology (FT) enables machining elements to carry both geometrical and technological information. Thus such features can improve the Product Development Process (PDP) by integrating Product Manufacturing Information (PMI) from the very beginning, avoiding redundant data storage and supporting the reuse of existing manufacturing knowledge. This paper reports the efforts undertaken by a German automotive OEM to establish Knowledge-based Engineering (KBE) in the PDP of their engines. More specific, bores are modelled as User-defined Features (UDF) in the CAD system Pro/Engineer, capable of being exported into the OEM?s production process planning tools. From there all necessary product, operation and resource information can be transferred directly into the OEM's working plan administrative system of the factories, due to the distinct feature definition and predisposed process description. In addition, a combination of CAD, CAPP and CAM libraries allows the storage of the manufacturing knowledge gathered during the actual production. For future product development projects these libraries may increase product design and production process planning celerity and reliability.
