Knowra Metalworking Metalworking Metalworking is the shaping, joining, cutting, or finishing of metal to make tools, structures, components, and decorative objects. It includes processes ranging from hand forging to automated machining.
Forging : Forging shapes metal through compressive force, often while the metal is hot. Hammering or pressing plastically deforms metal into a useful shape.
Metallurgy : Metallurgy studies metals, their properties, and the processes used to extract and modify them. Metalworking relies on metallurgical knowledge of structure and behavior.
Copper Age : The Copper Age was a prehistoric period when communities used copper tools alongside stone tools. Early copper objects mark some of the first deliberate metal shaping.
Blacksmith : A blacksmith forges and repairs objects made primarily from iron or steel. Blacksmithing applies hand forging to tools, fittings, and decorative work.
Additive manufacturing : Additive manufacturing builds objects by adding material, commonly in successive layers from a digital model. It creates metal parts by deposition rather than conventional cutting or forming.
Casting : Casting forms an object by pouring liquid material into a mold and allowing it to solidify. Molten metal can fill complex mold shapes that are difficult to forge.
Plastic deformation : Plastic deformation is a lasting change in shape caused by stress beyond a material’s elastic limit. Forging and rolling depend on permanent deformation without fracture.
Bronze Age : The Bronze Age was a period when bronze became a major material for tools, weapons, and objects. Bronze alloying expanded the range and durability of worked metal goods.
Sheet metal : Sheet metal is metal formed into thin, flat pieces by rolling or other processes. Cutting, bending, and joining sheet metal make enclosures and vehicle bodies.
Subtractive manufacturing : Subtractive manufacturing creates shapes by removing material from a workpiece. Machining is a major subtractive route within metalworking.
