Abstract Many functional properties of a cold rolled strip such as wear resistance, friction in a forming process, and optical properties depend on its surface finish. Accurate modelling of the real contact area is critical in predicting the surface finish of strips after cold rolling processes. The aim of this work is to experimentally verify existing contact models to predict the surface ...

Die stamping is a cold forming process that takes a sheet of metal, referred to as a blank or tool steel, and cuts and shapes it using a single or series of dies to create a desired shape or profile. The force that is applied to the blank modifies and changes its geometry, which creates stress that makes the workpiece suitable for bending or ...

The motivation of this study is to investigate micro warm coining of metals with high strength (e.g. austenitic steels) in the field of fabricating micro functional surface structures. The current micro cold coining technology, which uses punches made out of steel, is limited to soft metals, such as Al and Cu. Conducting micro cold coining on steels, leads to high tool wear and bad form filling.
