Metal forming
- In metal forming, the material is deformed plastically to generate the shape of the desired product.
- The important property of a material in metal forming processes is plasticity.
Forming operations
Forming operations are those in which the shape of a metal piece is changed by plastic deformation.
The following are examples of some common forming techniques:
- Forging
- Rolling
- Extrusion
- Drawing
Surface finishing processes
- The deformation is induced by an external force or stress, the magnitude of which must exceed the yield strength of the material.
- In a workshop, metal parts are manufactured by performing different operations in the lathe, shaping machines, milling machines, drilling machines, or grinding machines.
- In order to enhance the quality of the surfaces of these parts, several surface finishing processes are performed on them.
- Lapping
- Honing
- Superfinishing
- Polishing
- Buffing
- Scraping
- Electroplating
- Knurling
