This investigation was focused on the qualificationand quantification of effects andinteractions, which occur when miniaturisinga forming process to microscale. Up tonow, size effects usually have been investigatedisolated for single process parameters.Within the project, the interactions ofseveral characteristic process parameters(temperature, grain size, lubrication, punchvelocity and punch size) process have beendetected on the forming behaviour whileminiaturizing the process. A full factorialdesign of experiments has been used tocompare the reachable pin height at a fullbackward extrusion process for several differentparameter combinations. With theseresults, it was possible to determine anddescribe the different effects on the formingbehaviour. In addition to the investigation ofthe interactions, the design and the constructionof the experimental setup were afundamental element of this project.
