Blanking And Piercing
Blanking and piercing are shearing processes in which a punch and die are used to modify webs. The tooling and processes are the same between the two, only the terminology is different: in blanking the punched out piece is used and called a blank; in piercing the punched out piece is scrap. The process for parts manufactured simultaneously with both techniques is often termed 'pierce and blank'.
Famous quotes containing the word piercing:
“Old, aching God, grey with endless care,
calmly piercing evil’s new disguises,
glad of good surprises, wiser than despair
Hail and Hosanna, old, aching God!”
—Brian Wren (b. 1936)
