Short answer: Stamping defects — burrs from worn tools, cracks from brittle or too-cold material, springback from elastic recovery, twist and bow from uneven stress, and surface scratches from contaminated tooling — are the main yield killers in blanking, bending and deep drawing. Most are prevented by correct tool maintenance, material temper and process design: sharpen dies, anneal before severe forming, over-bend for springback, balance the draw, and keep tooling clean, with tolerances held per ISO fits and inspected by NDT.
