3. Automobile component
design
Introducing a new models of automobile
generally takes 3 to 5 yrs from inspection to
assembly.
Component designing is the first step for
production of all parts normally automobile
Parts vendors and manufactures do not make a
drawing of parts. They prefer CAD and CAM
software for this purpose.

Primary shaping Process :
In these process finish the product to its unable form
whereas others do not and required further working to
finish the component to desired shape and size.
Common process used in this are :
1. Casting
2. Forging
3. Power Metal Forming
4. Gas Cutting
5. Rolling

5. Machining Process :
These is a secondary process are mainly necessary when a
very closed dimensional accuracy and a very high degree of
surface finishing are required or some shape is to be
produced which is not possible through primary operation
This process are generally include:
1. boring
2. drilling
3. turning
4. threading
5. knurling
6. Planning

6. Joining process
These process are used for joining metal parts and general
fabrication work.
When steam or water tight joints are needed these process
are applied.
These common process are used in joining process are:
1. welding
2. Riveting
3. Soldering

7. Surface finishing
These process are used to metal removing
process to provide good surface finish and
decorative or protective coating on metal
surface although a very negligible amount of
metal removal or addition may take place the
common process are used to surface finishing
are :
1. grinding
2. lapping
3. honing
4. shaving

8. Conversion of raw material into parts
