Abstract
The focus of this paper is on pointing out the opportunities of a deeper interlinking of dimensional management into product-/ and production-development environment. Today, these opportunities are arising because of a reduction in hardware prototypes during the development process. Instead of prototype build-up a shifting into the digital CAx-world is performed, caused by the cut down of development time. To ensure the deeper interlinkage, an integrated approach is set up to efficiently optimize the data. Thereby data from both domains (product-/ and production development) is considered and the optimization is based on the results of a tolerance analysis. An implementation of the approach offers several opportunities. Tolerance analysis can then be used, to rapidly calculate several options which result out of a Design of Experiments of the optimization. This offers the possibility to increase the product maturity level at a very early stage of the development process.
