Study on Formability of Micro-Feature in the Coining Process

Abstract:

In micro-manufacture field, micro-forming is paid much attention due to its efficiency for mass production. However, owing to the particularity of deformation, mass researches for specialized micro-forming processes to direct the industrial production are of great urgency. As a similar process with the micro-forming, the forming property of micro-feature forming in coining process was investigated by the experimental research and numerical analysis. Firstly, utilizing the workpieces with different thicknesses and micro-feature sizes, the coining processes were numerically simulated to study the forming property of micro-feature. The height of micro-feature was selected as the evaluation criteria for the deformation behavior. Then, the pure copper specimens with different thicknesses were coined experimentally, using a die with a micro-hole by the universal testing machine to verify the simulation results. Finally, a modified scheme was successful to be proposed which could improve the manufacturability of the processes. The research results could provide technical references for manufacturing micro-parts and those with micro-features.
