- Material is neither added or removed in metal forming processes because in this process the metals are plastically deformed in hot or cold condition and the desired shape is obtained.

- Different types of metal forming processes are forging, rolling, drawing and extrusion.

- In surface finishing processes, material is removed but is considered negligible. This process is used to obtain good surface finish and dimensional accuracy.

- In casting process, molten metal is poured into the mould of desired shape.

- In machining process, material is removed to obtain the desired shape and component.
