Manufacturing Process may be classifies under following head.

(A).Shaping or Forming:-
-Manufacturing a solid product of define size and shape from a given material taken in three possible states:

→ In solid State:- eg. Forging, Rolling, Extrusion, Drawing etc.

→In Liquid or semi liquid state:- eg. Casting, Injection moulding etc.

→In powder from:- eg. Powder Metallurgy.

(B). Joining process welding, brazing,soldering etc.

(C).Removal Process
Machining( traditional or Non-traditional) Grinding

⇒Based on the nature of work involved these processes may be devide into following seven Categories:-
(1) Processes for changing Physical properties of the material:-

→Hardening, Tempering,Anneling,Surface Hardning.

(2) Casting Process:-

→Sand Casting, Centrifugal Casting Permenant Mould Casting, Die Casting.

(3)Primary Metal Working:-

→Rolling,Wire Drawing Forging, Extrusion.

(4)Shearing & Forming Processors:-

→Punching,blanking,drawing,bending,forming.

(5)Joining Processes:-

→Welding,Brazing,Soldering,Joining.

(6) Machining Processes:-

→Turning,Drilling,Milling,Grinding.

(7) Surface Finishing Processes:-

→Laping,Honing,Superfinishing.
