This review paper provides a comprehensive analysis of the various factors affecting micro-forming and parameters involved in manufacturing micro-parts. To ensure minimal wear tear error-free products, it is important to optimize both process framework. The aims highlight importance metal technology designing highly precise micro metallic devices, biodegradable implants, micro-pumps, gears. Thr...

this paper investigates the earing phenomenon in deep drawing of aa3105 aluminum alloy, experimentally and numerically. earing defect is mainly attributed to the plastic anisotropy of sheet metal. in order to control such defect, predicting the evolution of ears in sheet metal forming analyses becomes indispensable. in this regard, the present study implements the advanced yield criterion bbc20...

During the plastic deformation of brittle materials as magnesium, titanium or high strength steels, for instance in bending of sheet metals, the local strain can exceed the ductility – the strain at rupture – and thus cracks appear that eventually lead to rupture. Hot working would be beneficial since a temperature of a few hundred centigrades leads to an increase of the ductility by more than ...

In this work, thermal deep drawing and thermoelectric coupling tests were performed on an annealed ZK60 magnesium alloy sheet to investigate the effect of pulse current formability during process. The effects forming drawn parts studied, changes thinning rate hardness obtained. results showed that using improved increased ultimate depth drawing. value part overall increasing trend, followed by ...

When a sheet metal forming operation, such as deep drawing, is followed by a trimming operation the numerical springback is influenced by various physical parameters and numerical factors. Two techniques of taking into the account the stress state change due to cutting in the FE plate model are discussed in the present paper. The first technique concentrates on the effect of the element mesh cu...
