A method for removing the surface from a circular piece by bringing the cutting edge of a tool against it while the piece is rotated.
Forming, or metal forming, is the metalworking process of fashioning metal parts and objects through mechanical deformation; the workpiece is reshaped without adding or removing material, and its mass remains unchanged.Forming is usually done by plastic deformation.
Drilling is a cutting process that uses a drill bit to cut or enlarge a hole of circular cross-section in solid materials. The drill bit is a rotary cutting tool, often multipurpose.
The process of shaping metal by passing it between rolls revolving at the same peripheral speed and in opposite directions. In steel there are a number of different types of rolling mill for processing the ingot to its finished shape. These are variously known as Cogging mills, Slabbing mills, ...
In metallurgy, the process of shaping metal and increasing its strength by hammering or pressing. In most forging an upper die is forced against a heated workpiece positioned on a stationary lower die.Forging is actually a manufacturing process involving the shaping of metal using localized ...
In the context of machining, a cutting tool (or cutter) is any tool that is used to remove material from the workpiece by means of shear deformation. Cutting may be accomplished by single-point or multipurpose tools.
Volume defects in crystals are three-dimensional aggregates of atoms or vacancies. It is common to divide them into four classes in an imprecise classification that is based on a combination of the size and effect of the particle.
The two-dimensional defects that appear in crystals can be usefully divided into three types: free surfaces, which are the external surfaces at which the solid terminates at a vapor or liquid, intercrystalline boundaries, which separate grains or distinct phases within the solid, and internal ...
