Manufacturing Processes:

Importance of Manufacturing: The importance of manufacturing is that a gives usable product from the ore of different metals and from different material which cannot be used in their present condition.

2.Economic Definition : Manufacturing increase the value of product.

3.Technological Definition : Manufacturing is a process which gives required strength, shape and size of the product.

4.Survey of Manufacturing : A usable product is manufactured in the following sequence.

Ore from Earth → Reducing processes → Molten metal → Commercial Castings → Ingots → Further Processes → Usable product of different shapes and sizes.

All these further processes used for changing the ingots into usable products can be classified as follows :

 1.  Primary Shaping Processes                                 2.Machining Processes

 3..Joining Processes                                                4.Surface Finishing Processes

 5.Processes effecting change in properties
