Study on forming uniformity of multi-electromagnetic forming (EMF) of aluminum sheet metal

Electromagnetic incremental forming (EMIF) is employed for forming large-sized parts of aluminum. The basic characteristic of EMIF is multi-electromagnetic forming (EMF). The forming uniformity of a multi-EMF is the key to the success of an EMIF method. In this study, first, several important parameters affecting the forming uniformity of single EMF are studied using orthogonal experimental research scheme. In order to conduct a comparative study on the forming uniformity of the multi-EMF, two-coil moving strategy is selected. Thereafter, the effect of overlap ratio on the forming uniformity of the multi-EMF is studied using the coil sequence moving strategy. The effect of shaping voltage is also investigated using the coil spaced moving strategy. Based on the findings, the optimum conditions of forming uniformity of the multi-EMF are obtained. An experimental verification of the simulation results is also conducted. The obtained results present a viable method and guidance for EMIF of large-sized aluminum alloy sheet metal parts.
