Abstract: With the further miniaturization of the manufacturing limit, micro-forming just by loading of the tool (force field) becomes more and more difficult and the limit of the forming scale cannot be broken. Therefore, there is an urgent demand to develop new
principles, methods and processing technics in micro-forming. Aiming at the fundamental scientific problem of size effects in microforming, nontraditional energy fields such as electric field, electromagnetic field and ultrasonic are introduced to micro-forming technology. The new effects of interaction between energy fields and materials will be used to break through the scale limit and expand the range of materials to achieve multi-scale, multi-material and controllable micro-forming. The development of energy field assisted micro-forming technology will significantly promote the evolution and application of micro-forming technology and becomes an important development trend in the field of micro-nano manufacturing technology.
