Abstract Scope |
Within this paper, multi-stage bulk microforming from sheet metal is investigated for the fabrication of metallic micro parts in laboratory scale with the material Cu-OFE. In a first step, the process-influencing variable of the blank holder pressure is analysed in the first forming stage in order to derive measures for the highest possible material utilization. The two-stage forming of the pin with cup is compared with a single-stage process to assess the part quality and material utilization depending on the process strategy. Using the correct geometric scaling, size effects are identified and their effects on the forming process are evaluated. The experimental results reveal that it is possible to fabricate micro parts with a diameter of 470 µm and a minimum wall thickness of 36 µm reproducible by using the presented cold bulk microforming process strategy. |
