CNC Machining is a rapid process in which a material is cut to a desired final shape and size by a controlled material removal process.
The processes that have this common theme are collectively called subtractive manufacturing, which utilizes machine tools, in contrast to additive manufacturing), which uses controlled addition of material.
The principle of CNC machining of aluminum alloy is to use the automatic control system to install a digital program process to control the automatic start-stop, reversing, and speed change of the machine tool. Machining can select CNC tools, and change the tool holding force and walking trajectory according to the CNC tools to complete various actions required in processing. CNC machining of aluminum alloy products, 90% of the products can be completed independently by CNC machine tools, and do not need to be processed by other machines.
Machining is a part of the manufacture of many metal products, but it can also be used on other materials such as wood, plastic, ceramic, and composite material. A person who specializes in machining is called a machinist. A room, building, or company where machining is done is called a machine shop. Much of modern-day machining is carried out by computer numerical control (CNC), in which computers are used to control the movement and operation of the mills, lathes, and other cutting machines. This increases efficiency, as the CNC machine runs unmanned therefore reducing labor costs for machine shops.
