Influence of tool elastic deflection during micro-forming of metallic components

Abstract

The trend of miniaturization has increases over the past decade due to increase in demand of micro parts in many industries. This has lead to micro-forming processes to be more prominently applied. However, basic research has shown that conventional metal forming knowledge cannot be applied to micro-forming processes due to the size effect.

This final year project was carried out to study the effects of elastic tool deflection on the dimensions on the manufactures micro-formed parts. Methodology for studying this was proposed and the analysis was carried out using the computing tool, ABAQUS/STANDARD. Several factors such as final dimensions and reaction forces were studied to determine and assess whether elastic tool deflection does affect micro-forming processes.

Simulation assessment has led to the conclusion that elastic tool deflection does affect the final dimensions to a certain extent. Conclusion and recommendations were also put forth.
