Machining is a process that consists of abrading, cutting, drilling, forming, grinding, and/or shaping of a piece of metal or other material performed by machine tools such as lathes, power saws, and presses. While most machining involves taking away a portion of the part to make it perfect, machining can also be used to add material to a piece.
Machining is part of the manufacturing of metal products, but it can also be used for other materials such as wood, plastic and composites. Much of modern day machining is now CNC (Computer Numerical Control) where a computer controls the machinery used to create the finished part.
Once the piece is cast, the unfinished workpiece will require machining in order to match the original specifications set out in the engineering drawings. For example, a certain part may be required to have a specific outside diameter. While the original casting can be close to that specification, with the shrinkage involved in casting it usually cannot be exact. The piece can then be put on a lathe which is controlled by a computer to cut and polish the exterior diameter to ensure the exact size and finish specified in the original engineering blueprints. Other machining tools include drills, milling machines, saws and grinding machines.
