Trimming and Sheared Edge Stretchability of Light Weight Sheet Metal Blanks

Slanted Blades Optimizing Grain Texture and Work Hardening of Non‐Oriented Electrical Steel in Stress Coverages during Shearing and Blanking Processes

“…The two bands were similar to common incisions cut by flat blades. [14,15] Except the smooth cut sections with unidirectional scratches, the tensile failure zones existed usually on the other parts of cut sections. The incision surfaces cut by the 45 blades revealed bright bands with different directions, as shown in Figure 1b,e.…”
