What distinguishes sheet forming from bulk forming?
The key difference between the sheet forming and bulk forming.
Explanation of Solution
In sheet forming processes, the load is applied to the particular part of the material to transform the shape of the material rather than removing some portion of material from it, sheet forming includes,
- Bending
- Roll forming
- Deep drawing
In bulk forming processes, load is applied for the large variation in the shape of the material. It is often done in the hot operating situations. Bulk forming includes,
- Rolling
- Forging
- Extrusion
- Wire or rod drawing
The key difference in the sheet forming and the bulk forming is ratio of area to that of the volume. The ratio of area and volume in the sheet forming is high whereas in the bulk forming, the ratio is less.
