ABSTRACT
A high-energy-assisted microforming system, which combines heating and vibration, was developed to improve the efficiency and accuracy of microscale metal parts. The system consists of a desktop servo-press system that can supply various motions including step and vibration motions and a resistance-heating system with contact electrode probes embedded in the dies that are capable of heating only the workpiece and of real-time control. Microdeep drawing and microforging was conducted to evaluate the performance of the high-energy assistance. The formability was found to improve significantly, and the surface roughness improves due to improved flowability and deformation uniformity.
