A lot of people can hardly imagine how important these technologies are in their lives: it is present in products and objects of everyday life as e.g. cars, airplanes, components of machines of all types, moulds for tools used for household machines, cell phones, toys, medicine prosthesis, etc.CNC Technology includes machining tools such as lathes, multi-axis spindles, wire electrical discharge machines and milling machines, where the functions formerly performed by human operators are now performed by a computer-control module. The professionals associated to this skill use computer numerically controlled (CNC) machines to cut and shape precision products, as mentioned above. To form a finished part the cutting process can be started from a solid block, premachined parts or castings.Thus the abbreviation (CNC) refers to a computer (""control"") that reads instructions (""G-code"") and drives the machine tool, a powered mechanical device (""milling machine""), used to fabricate components by the selective removal of material. A programme with "G-codes" is required and generated manually and/or automatically using CAD/CAM software followed by the necessary machining operations.Today a wide range of industries require CNC milling professionals to program, operate and keep sophisticated milling machines running in an efficient and reliable way. Large enterprises such as automobile, medium-sized enterprises, such as mould making and small enterprises on maintenance field are some of many examples where the CNC milling professional plays a key role to the success of metalwork industry.
