| Abstract Scope |
Shear cutting induces high strains and work hardening into the shear-affected zone, thus reducing the formability of the sheet metal material during subsequent forming operations. A common method for increasing the residual formability of shear-cut component edges is to shave the surfaces. The shaving process allows highly hardened areas to be removed from a pre-cut contour, resulting in a comparatively high residual formability of the cutting surface. However, as with normal cutting, a burr remains on the shear surface when shaving. For this reason, a new process has been developed which combines counter-cutting and shaving, enabling the production of burr-free shear surfaces having high percentages of clean-cut proportions and significantly higher hole expansion ratios (factor 1.7) than conventional cutting surfaces. The present paper deals with numerical and experimental investigations carried out in the course of the process development with the high strength sheet metal material DP600. |
