Abstract

In this paper experimental investigations on micro components that are made by rotary swaging are presented and discussed. At first rotary swaging with its most important process variations is explained basically for the macro scale. Afterwards the fundamental changes of the forming of microcomponents are indicated as well as the smaller machines used henceforth. In this context, the shown process limitations and potential errors are very important. The change in microstructure after rotary swaging is shown in selected geometry and materials. The paper concludes with the planned experimental and analytic investigations as well as the machine design modifications for extension of the process limits of micro rotary swaging.
