Although elastic springback makes a great challenge in sheet metal forming, it is also a value that is considered in the area of coining. It is a parameter that can often make many difficulties when coin should obtain the etching of the die. That can happen because of small coin height in which leading part takes material composition, its grain size and microstructure. It classifies coining process to a group of microforming processes. Therefore, an experiment has been carried out whose task was to provide data about percentage of elastic springback in total deformation during coining process of Al 99.5%. This has been carried out for three different grain sizes of the same material. An experiment has also included microscopic observation of gravure filling for mentioned grain sizes and also for different tool forces. The final result is a correlation between grain size and elastic springback in coining process, and also a correlation between grain
size and gravure filling for different tool forces.
