🛠️ Bead Roller: Bead Profile, Section Stiffness, Strain and Feed Kinematics (2D)

Side view of a hand-cranked bead roller whose two synchronised dies roll a bead into sheet metal, beside an enlarged bead cross-section. Set crank speed, die radius, sheet thickness, bead depth and width, panel width, span and load, and see the roll surface speed, the strain across the bead and how much the bead stiffens the panel. Arc geometry, section second moment and beam deflection are computed, with four in-page numerical checks. A manufacturing companion to the 3D bead roller.
