A methodology and new criteria to quantify the adhesive and abrasive wear damage on a die radius using white light profilometry

► Wear of different tool steels is investigated using a hot-stamping simulator. ► Methodology is developed to assess the wear on the die-radius tools. ► Profile measurements are performed using a white-light source profilometer. ► Four new criteria are defined to quantify both adhesive and abrasive wear. ► This method allows to classify different tool steels with a good reliability.
