Abstract
The electromagnetic incremental forming (EMIF) method is used for tube forming process.
Suitable 2D FE models are designed to predict the forming process with a moving coil. In
comparison with experimental values, simulation method can obtain accurate results. Then,
effect factors named overlapping ration of adjacent discharge positions, discharge voltage,
forming sequence and die dimension on tube homogeneous deformation are discussed. The
result demonstrates that it is feasible to produce long-straight wall tubes using a small coil by
electromagnetic incremental tube bulging.
