This mainly results in micro-plowing and plastic extrusion flow, leading to lower friction coefficient. However, when wall angles exceed 40°, significant plastic strain roughening occurs, leading to inadequate lubrication on the newly formed surface. Increased sheet thickness and decreased tool radius elevate contact pressure. These actions trigger micro-cutting and adhesion, potentially leading to localized scuffing and dimple tears, and higher friction coefficient.
