Hello students, the first question is that what are the desirable properties of metals which are subjected to metal forming operations.
00:08
So the desirable properties are ductility, ductility, then malleability, formability, then strength, hardness, wear resistance.
00:43
These are the characteristics.
00:45
Now the second question, what is the difference between bulk deformation and sheet metal working? so bulk deformation is a process, deformation is a process.
00:56
It's a forming of parts in which the entire mass of the material is changed to create a new shape or size.
01:03
That is if you break down, so it's bulk deformation, right? so bulk deformation, if you break down the entire mass to form a new structure, that is when you call it bulk deformation.
01:20
Now sheet metal working is a process wherein sheet is what to create a desired shape by cutting.
01:27
So sheet metal working is when you cut a sheet, okay, into desired shapes and then fold it or fold it or redesign it to become something by pressing or something...
