The operation performed on sheet to get required shape called sheet metal operation. In operation the metal gets sheared so it is also called as shearing operation.

Major operations :

1) Punching

2) Blanking

3) Deep Drawing

Minor operations :

1) Perforating

2) Notching

3) Slitting

4) Lancing

5) Nibbing

6) Trimming

7) Shaving

1) Punching :

In this sheet metal operation the blank produced is waste part and the hole produced on sheet is required.

This is used to produce hole of different size and shape on sheet metal.

2) Blanking :

4) Shaving :

shaving is done to remove the unwanted or excess material left from the periphery of formed component.

5) perforating :

The method of producing many number of smaller size holes in sheet called perforating.

6) Notching :

The method of removing a piece of material from the edge of sheet called notching.

7) Slitting :

The method of producing incomplete hole or blank at the edge of sheet called slitting.

8) Lancing :

The method of producing in-complete hole or blank at the centre of sheet is called lancing.

9) Nibbing -

The method of producing large size hole using small size punch in many number of repetitive strokes called nibbing.

10) Trimming :

The method of removing small amount of material from complete circumference of sheet is called trimming operation on edge trimming operation.
