Introduction to various manufacturing process

1. Manufacturing Process

2. Manufacturing Process
• Manufacturing is the conversion of raw
materials into finished product to be used for
some purpose.
• Manufacturing some time involves a group
operations to produce the finished product
which can be put into service.
• Economics is very very important in every
manufacturing process.

3. Classification
• Manufacturing processes are classified into
following categories
- Casting process
- Forming process
- Fabrication process
- Material removal process

4. Casting Process
• Casting processes are further classified into
following categories:
- Sand casting
- Shell mould casting
- Investment casting
- Plaster mould casting
- Permanent mould casting
- Die casting
- Centrifugal casting

5. Forming Process
• Metal forming processes are further classified
into following categories:
- Rolling
- Forging
- Extrusion
- Wire drawing
- Sheet metal operations

26. Material Removal Process
•A family of shaping operations through which
undesired excess material is removed from a
starting work piece so the remaining part become
closer to the desired shape are called as metal
removal processes and they are classified as
follows:
- Turning
- Drilling
- Milling
- Grinding
- Sawing
