In contrast to traditional manufacturing applications, small-scale manufacturing processes usually require sophisticated equipment, which generally involves high cost and low productivity. On the other hand, miniature stamping processes of thin materials can yield high productivity with relatively inexpensive equipment. However, it is well known that the formability of thin material using this type of process is not very good, and the possible shapes that can be produced via miniature stamping have, until now, been relatively simple. This study was motivated by the presumption that, if the problems related to formability can be solved, then miniature-scale stamping of complicated shapes can be realized. This research was carried out to demonstrate the feasibility of miniature stamping, and mainly focused on formability aspects. To improve formability, annealing was chosen as a means of improving the material properties, and the use of optimal blank shapes was chosen as a means of addressing process issues. Optimal annealing conditions were identified by examining the microstructures of the annealed material, and the optimal shape of the blanks was determined using the radius vector method. The combination of the annealing improvements and the use of optimal blanks improved the formability considerably. Therefore, both the annealing process and the blank shape are key technologies in the development of more effective miniature stamping processes.
