Engineering Angle: Measuring friction for stamping of UHSS

Researchers at Oakland University studied how the coefficient of friction between tool steel inserts and ultrahigh-strength steels (UHSS) sheet is influenced by lubrication thickness, sliding speed, and contact pressure. The use of UHSS for automotive components has increased rapidly in recent years because of their structural performance and light weight, but their formability is constrained compared to mild steels.
