Metalworking generally is divided into three categories: forming, cutting, and joining. Most metal cutting is done by high speed steel tools or carbide tools. [7] Each of these categories contains various processes. Prior to most operations, the metal must be marked out and/or measured, depending on the desired finished product.
Machining is a manufacturing process where a desired shape or part is created using the controlled removal of material, most often metal, from a larger piece of raw material by cutting. Machining is a form of subtractive manufacturing , [ 1 ] which utilizes machine tools , in contrast to additive manufacturing (e.g. 3D printing ), which uses ...
Identifying a problem at an early stage in the production process allows for correction and preventative action to avoid wasted time and resources at the end of a production run. Statistical Process Control complements process manufacturing and in process inspections to ensure that the process operates efficiently, producing more specification ...
Steel mill with two arc furnaces. Steelmaking is the process of producing steel from iron ore and/or scrap.Steel has been made for millennia, and was commercialized on a massive scale in the 1850s and 1860s, using the Bessemer and Siemens-Martin processes.

Shearing, also known as die cutting, [1] is a process that cuts stock without the formation of chips or the use of burning or melting. Strictly speaking, if the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations. [ 2 ]
