Blanking (metalworking)

Blanking (metalworking)

Blanking is a shearing process where a punch and die are used to create a "blank" from sheet metal or a plate. The process and machinery are usually the same as that used in piercing, except that the piece being punched out in the piercing process is scrap.Degarmo, p. 427.]

Fine blanking

Fine blanking is a specialized form of blanking where there is no fracture zone when shearing. This is achieved by compressing the whole part and then an upper and lower punch extract the blank.Degarmo, p. 425.]
