“…This was inconsistent with the result obtained by Wang et al [12], as they concluded that the surface roughness of monolithic copper sheets formed by laser shock always increased with increasing feature size. It was also in disagreement with the conclusion in quasi-static loading illustrated by Fu et al [18], as they found surface roughness of monolithic copper sheets increasingly larger with decreasing mold size. This could be due to the fact that, the surface roughness of two-layer metal composite sheets is decided by the deformation extent of the external layer rather than the entire sheet.…”

“…As such, it is critical to investigate the size effect on the deformation behavior of materials. Many scholars have conducted investigation on the size effect phenomenon, including grain size effect, specimen size effect, and feature size effect [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”

“…Xu et al [17] found that surface quality and irregular geometry shape worsened with the feature size of the formed cup decreasing under the micro deep drawing process. Fu et al [18] researched the influence of punch radius on forming load during the micro compound process of blanking and drawing. Wang et al [12] and Liu et al [19] studied the feature size effect on the micro forming process of thin copper foils under laser flexible dynamic loading.…”

Abstract:Multilayer metal composite sheets possess superior properties to monolithic metal sheets, and formability is different from monolithic metal sheets. In this research, the feature size effect on formability of multilayer metal composite sheets under microscale laser flexible forming was studied by experiment. Two-layer copper/nickel composite sheets were selected as experimental materials. Five types of micro molds with different diameters were utilized. The formability of materials was evaluated by forming depth, thickness thinning, surface quality, and micro-hardness distribution. The research results showed that the formability of two-layer copper/nickel composite sheets was strongly influenced by feature size. With feature size increasing, the effect of layer stacking sequence on forming depth, thickness thinning ratio, and surface roughness became increasingly larger. However, the normalized forming depth, thickness thinning ratio, surface roughness, and micro-hardness of the formed components under the same layer stacking sequence first increased and then decreased with increasing feature size. The deformation behavior of copper/nickel composite sheets was determined by the external layer. The deformation extent was larger when the copper layer was set as the external layer.

“…In micro deep drawing process due to size-effect and its new concerns, it is compared to macro deep drawing while experiments have shown under the same forming conditions the friction coefficient in micro deep drawing is greater than that in macro deep drawing (F.

Nowadays, there are increasing demand on micro-systems, micro products/components and micro-devices. Thus, the role of micro manufacturing in all aspects of modern industry is taken for granted. Then, typical processes in micro manufacturing are discussed. Furthermore, one of the most widespread micro-manufacturing processes in deforming processes is micro forming that is presented in this paper. Finally, besides continuing effort in developing micro forming, this paper strives to analyze systematically the key methods of stamping, bending, forging and deep drawing processes and their prominent issues.

The Investigation on Mask and Plasticine Laser Shock Forming

et al. 2016

View full text Add to dashboard Cite

Abstract.A novel technology called mask and plasticine laser shock forming (MAPLSF) was introduced to manufacture micro-features on the surface of pure copper foil with the thickness of 40ȝm. In this process, the laser-generated shock wave and plasticine are used to replace the conventional rigid punch and die. The result showed that the shape of laser beam can be roughly manufactured on the surface of the workpiece and this mold-free laser shock forming process is a fast method to fabricate controlled micro-feature on the metallic foils. In this damage-free forming process, the workpicec can keep good surface, because the plasticine is softer than metal foils.
