“…Bouchaâla et al. [ 167 ] investigated the effect of anisotropic and isotropic yield functions of AA2090 Al–Li alloy on the thickness distribution during sheet metal forming process. Many phenomenological yield functions have been proposed to predict the anisotropic plastic behavior of the sheet metal forming (e.g.…”

Meso-and microforming is a technology to shape parts from extremely small metal billets. Parts with geometric dimensions are a few millimetres to a few micrometres. With the rapid development of the electrical-electronics industry and biomedical engineering, the technology of forming microscopic parts has been researched and applied because of its efficiency, accuracy, and high productivity. Deep drawing is an operation that turns flat sheet metal blanks into hollow, open-mouth parts. It is an essential process in sheet metal stamping. Micro deep drawing is one of the micro-shaping technologies that has been widely studied and applied in recent years. However, the bases for calculating technological and geometrical parameters in the micro-deep drawing have not yet been analyzed and evaluated in detail. Therefore, this paper has proposed a theoretical basis combined with simulation applied to the design of technology to manufacture a connector head part drawing die with a diameter of 300µm and height of 1500µm using materials SUS304 material. Numerical simulation also allows evaluation of the stamping part's internal stress state, the ability to pull the workpiece into the die, and the thickness distribution on the product wall. Experimental research has also verified that, with the determined parameters, the stamping parts meet the quality requirements. This indicates the proposed calculation methods for the tiny deep drawing operation are entirely suitable. The results of this research can be wholly applied to the production of micro-sized cylindrical cup parts using the deep drawing method.

“…Therefore, the accurate prediction and control of the parameters in the micro-forming process are essential. (1)(2)(3) Sheet metal forming is currently divided into four basic models, (4) namely, stretching, drawing, stretch-flanging, and bending. A sheet metal is subjected to different forces for different forming models, and various formability tests are utilized to evaluate the formability of sheet metal in an actual stamping.…”

For the design and fabrication of dies by the deep drawing process, the problems of springback after load removal and the formation of cracks must be considered. In this study, a deep drawing process for micro square holes on copper sheets was analyzed on the basis of an updated Lagrangian formulation and 3D finite element analysis. Sheet behavior was simulated using a micro-elastoplastic material model, the performance of which was compared with that of models involving conventional materials. Subsequently, Dynaform software was used for simulation analysis to obtain the material deformation history as well as determine the thickness change distribution and the maximum stress and strain of a copper sheet. It was found that the punch fillet radius and forming ratio affect the relationship between the punch load and the punch stroke, the distributions of stress and strain, and the maximum flange height. Finally, simulation results were compared with experimental results to confirm the accuracy of the 3D finite element analysis of the elastoplastic deformation. The results show the effect of the punch fillet radius for copper sheets on the drawing process: when the punch fillet radius is small, the punch load increases and decreases more rapidly. The maximum stress and strain decrease as the punch fillet radius increases. These findings serve as a valuable reference for design and processing by micro deep drawing.
