This article presents the results of studies on friction conditions at the rounded edge of stamping dies in sheet metal forming. Using a friction tester developed by the authors to perform a bending-under-tension test, low-carbon steel sheets were examined under dry fric-tion conditions. Changes in friction conditions were achieved by producing functional sur-faces on the countersample surfaces using electron beam melting and ion implantation. The coefficient of friction was determined using two strategies: with a stationary countersample and with a freely rotating countersample. The influence of the surface treatment of the coun-tersamples on friction-induced changes in the surface roughness of the sheet metal was also evaluated. The difference in the friction coefficient between the two analyzed friction test strategies ranged from 1.78% to 8.51%, depending on the type of friction pair. Similarly, the friction process led to an increase in the mean surface roughness Sa (by 1.34–16.7%) and the skewness Ssk (by 9.7–70.9%). Depending on the friction pair type and the method of coun-tersample mounting, the strain-induced kurtosis Sku of the strip samples decreased by 10.2–42.4%.
