Abstract

The conventional stamping manufacturing process, certain limitations need to be considered throughout the product's design process. If the restriction is not considered, they turn into the defect, which costs a lot. Alternatives to overcome the defects are changing the material composition, thickness of the material, or the product design. This research aims to reduce the defects by keeping the design and the material the same as considered during the design phase. Electrically assisted manufacturing is used in the stamping process to eliminate defects. In this process, the current is passed through the blank, which will heat the blank. The heat produced due to electricity will temporarily change the material and increase its elasticity. Once the temporary elastic limit is achieved, the stamping process will begin. The current flow in pulses will continue until the stamping is completed. Further work includes deciding the exact amount of current and time to pass the pulses, ensuring that the material will not permanently change its properties.
