Environmental friendly manufacturing is not limited to clean processes. For active products, like a car, the environmental impact of the use-phase can be more than 100 times higher then the environmental impact of the manufacturing-phase. The manufacturing design should therefore also be directed to the optimisation of the environmetal performance of the product. In the automotive industry one of the possibilities to realise this, is the application of tailor-made blanks (TMB). TMBs reduce both the part weigth and the production waste. Both aspects contribute to a better environmental performance. One of the imporatant decisions in the TMB-design concerns the weld position. The present study concentrates on the relation between the weld position and the environmental performance and the relation between the weld position and the formability, defined as the maximum product heigth in deep drawing. A modular tool has been designed, with which different material combinations and weld positions are tested. Finally the test results are combined with the results of the environmental analysis and is the formability behaviour related to the environmental performance of the TMB.
