Question

Component design for blanking operation.

Answer 1

Blanking and piercing are shearing processes in which a punch and die are used to modifywebs. 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.[1] The process for parts manufactured simultaneously with both techniques is often termed "pierce and blank." An alternative name of piercing is punching
