CAMM researchers recently studied die wear in 3D-printed tools during room-temperature stamping of aluminum alloy 5754 sheet.

CAMM researchers used the U-bend process to investigate die wear behavior during room-temperature stamping of aluminum alloy sheet AA5754.

Researchers at Oakland University studied how the coefficient of friction between tool steel inserts and zinc-coated UHSS sheet is influenced by lubrication thickness, sliding speed, and contact pressure.

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.
