Abstract

Micro forming is a very sensitive and applicable process to fabricate products with less than 1mm dimensions. Some challenges like gripping and tool design need more investigation. The sheet hydroforming method can be replaced instead of cup/deep drawing for fabrication of complex shape products. In this paper, research on micro sheet hydroforming work has been introduced and explained. A final element simulation has been carried out for deformation of a micro cup with 0.05mm thickness. A micro hydroforming setup has been designed and fabricated based on results of simulation. Result of FEM simulation has been good agreement in comparison with experiments by the setup.
