特种能场微成形技术研究进展

随着微成形加工尺度范围的不断延伸，单纯依靠模具施加载荷(力场)的微成形技术难以突破成形尺度极限，因此迫切需要发展塑性微成形新原理、新方法和新工艺。针对微成形尺度效应这一基本科学问题，将电场、电磁场和超声波等特种能场应用到微成形技术中，利用特种能场与材料相互作用产生的物理效应，突破微成形尺度极限并扩大可加工材料的范围，从而实现跨尺度、多材料和可控微成形。特种能场微成形技术将极大地促进微成形技术的发展和应用，成为微/纳制造技术领域一个重要研究方向。

Research progress on nontraditional energy field micro-forming

With the further miniaturization of the manufacturing limit, micro-forming just by loading of the tool (force field) becomesmore 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.
