Metal manufacturing, is the creation of metal structures by different processes like cutting, bending, stamping, forging, casting and additive manufacturing from various raw materials.
A sought out process is subtractive manufacturing which is a removal processes that starts with a solid block, bar, rod that is shaped by removing material manually or by a automated
CNC process (Computer Numerical Control) shaping the raw material into a part that was design in a 3D CAD data format. The other side of the coin would be Additive manufacturing which is the process of sintering layer by layer of the raw metal powder turning into the CAD model.
