Contactless high speed metal forming by means of a pulsed
electromagnectic field. The forming process takes place in typical less than
70 μs, the camera exposure times were varied within one sequence between 500 ns
and 2 μs to accommodate for changes in forming speed and light intensity due to metal reflections.
The influence of the key process parameters magnetical field strength and mechanical
setup on forming dynamics was studied.
