Abstract
Micro impact extrusion is investigated at Chemnitz University of Technology as a potential procedure for large area machining of micro cavities within the scope of the Collaborative Research Centre SFB/Transregio 39 PT-PIESA of the German Research Foundation. Applying impact extrusion, micro forming is done by material flow opposite to the effective direction of the force exerted by the tool. Therefore, no structured die plates are necessary, but high forming forces are required. In this study the influence of process parameters is investigated.
