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
