Oakland University researchers investigated wear in coated and uncoated punching inserts when stamping aluminum alloy sheet AA5754, typically used for lightweight automotive structural parts.

Oakland University researchers studied combinations of die material, die surface treatment, and lubricant to determine how best to prevent galling when stamping aluminum automotive structural parts.

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.

Oakland University researchers explore how trimming clearance, material type, material anisotropy, and tool wear affect sheared edge quality in stamped parts.

Researchers analyze how restraining force can be adjusted by changing the draw bead penetration.

Sheared-edge cracking is a challenge when stamping advanced high-strength steels (AHSS). Four test methods can be used to assess sheared-edge stretchability, giving stampers data that can help them with material selection at the design stage.
