Abstract
There is little disagreement that better understanding and early incorporation of production variation data into design and development is conducive to success. However, existing process capability databases (PCDB) are largely unused for design purposes so far. To overcome this situation and to support the early application of approaches, such as Tolerancing, Robust Design, etc., challenges as well as the potential benefits of PCDBs in design are examined. The applicability of an elaborated new PCDB-structure is then analysed using a test-data base with examples of injection moulded parts.
