WebCut Edge Quality. Any mechanical cutting operation such as blanking, piercing, shearing, slitting, or trimming reduces edge ductility. Each of these processes generate a zone of high work hardening and a reduced n-value. This work hardened zone can extend one-half metal thickness from the cut edge. http://www.production-resources.com/pdfs/PRI-formulas.pdf
