Electromagnetic forming (EMF) is a high strain-rate forming method where a pulsed
electromagnetic force is applied to a conductive metallic workpiece. To improve the
performance of the EMF system, the current problems which restrict its extensive
application have been analyzed. To this end, a space-time-controlled EMF technology
with multi-stage and multi-direction coils system has been developed. In our new EMF
system, the magnetic field generated by driving coils is much higher than in conventional
EMF due to introducing design methods developed for non-destructive pulsed high field
magnets. This technology enables the forming of complex, large-scale sheets and tubes
that may be difficult to deform by conventional methods, as well as controlling particular
properties of the work pieces
