Although there is considerable published literature on micro-metal forming processes, there
is still a lack of research towards implementing these processes commercially. Some of the …

The precise prediction of springback is a key to assessing the accuracy of part geometry in
sheet bending. A simplified approach is developed by considering the thickness ratio …

The grain size often influences the precision and quality of products manufactured by
microforming at the microscale. Macroscale finite element modeling (FEM) cannot accurately …

The current study on free bending focuses on traditional macroscopic tubes and profile
components. Nevertheless, as the geometric size of the tube decreases, the resulting size …

The determination of the accuracy of part geometry is based on the precise prediction of the
springback–radius in sheet bending. Incorporating strength ratio, normal anisotropy, the …

In this paper, the bending index for micro-tubes is presented by experimental and numerical
investigations. For this purpose, the dimensionless relationship of the bending index has …

The deformation behavior of microtubes during hollow sinking was investigated to clarify the
mechanism of the excessive thinning of their outer diameters. Stainless-steel, copper, and …

Springback is an inevitable phenomenon in bending operations. For the geometrical
accuracy in manufacturing, springback should be predicted and a required compensation …

This article investigated the effect of process parameters, including grain size, punch radius
and punch speed, on springback in micro V-bending. The effect of yield strength, directly …

The bending process of an industrial connector is considered and investigated via numerical
simulation using a crystal plasticity finite element model (CPFEM). The process consists of …
