TYPE OF DIE CUTTING OPERATIONS

The operations of die cutting shearing of work materials are classified as follows :

Piercing Punching

Is the operation in which a round punch, or of other contour, cut a hole in the work  material which is supported by a die having an opening corresponding exactly to the contour of the punch.

The material slug cut from the work material is often scrap.

Blanking

Fundamentally differs from piercing only in that the part cut from the work material is usable, becoming a blank workpiece for subsequent press working or other processing.

Lancing

Combines bending and cutting along a line in the work material.

It does not produce a detached slug and leaves a bent portion, or tab , attached to the work material.

A cutt off

Operation achieves complete separation of the work material by cutting it along straight or curved lines.

A notching

Operation cuts out various shapes from the edge of workpiece material a blank or part.

Shaving

Is a secondary shearing or cutting operation in which the surface of a previously cut edge of a workpiece is finished or smoothed.

Punch and die clearance for a shaving die, considerably less than that for other cutting dies, allows a thin portion or shaving to be cleanly cut from such a surface of workpiece.
