Electromagnetic forming is a high speed forming process that is already established in the macro world. Due to its advantages like high deformation rate and cheaper tools it is introduced to micro forming. In this research the replication of prismatic optical microstructures is investigated. EN AW-1050A (Al99.5) micro metal sheets with a thickness of 50 µm and 300 µm are electromagnetically micro embossed. The microstructures of the embossing tool are generated by Diamond Micro Chiseling (DMC), a new machining process to generate discontinuous microstructures like miniaturized cube corner retro reflectors and V-shaped grooves with defined endings. For the replication, electromagnetic body forces are used. With this technique, it is possible to successfully replicate triangular cross-section micro V-grooves of 86.6 µm in width and 24.1 µm in depth.
