Finite element (FE) simulations can be used to predict the occurrence of fracture or wrinkles in a given deep drawing.

The researchers at CPF explore the effect of draw beads and spacers in deep drawing and explain why they aren’t used in progressive die drawing.

Editor’s Note: Part I appeared in the July/August 2018 issue and discussed the effect of process variables in blanking (piercing).

Researchers at The Ohio State University explore how material, punch/die clearance, and tool wear affect edge fracture during hole extrusion and flanging.
