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:
“O falling fire and piercing cry
and panic, and a weak mailed fist
clenched ignorant against the sky!”
—Elizabeth Bishop (1911–1979)
