Probabilistic Assessment of Defect Origination while Burr Trimming and Scrap-Bridge Punching in Axisymmetric Stamped Pieces

摘要

There are offered probabilistic models of prediction of defect origination while burr trimming and scrap-bridge punching in axisymmetric pieces stamped in hot-forming crank presses. There is presented an example of assessment of technological failure probability dealt with excess of upper limits of end burr size while burr trimming and depth of imprint on stamped piece surface due to pressure or piercing punch action.
