Precision machining is the process of removing material from a workpiece while maintaining precision tolerance finishing. There are many types of precision machine tools, including milling, turning and electric discharge machining. Precision machines are currently controlled using computer numerical control (CNC).

Precision machining to provide parts and components for aviation aircraft. Almost all metal products use precision machining, as do many other materials such as plastics and wood. These machines are operated by professional and trained mechanics. In order for the cutting tool to work, it must be moved in the specified direction for proper cutting. This main action is called "cutting speed". The workpiece can also be moved, called the secondary motion of "feed". These actions together with the sharpness of the cutting tool allow precision machines to operate.

High-quality precision machining requires the ability to follow extremely specific blueprints created by CAD (Computer Aided Design) or CAM (Computer Aided Manufacturing) programs such as AutoCAD and TurboCAD. The software helps create complex 3D charts or contours needed to make tools, machines or objects. These blueprints must be strictly adhered to to ensure the integrity of the product. Although most precision machining companies use some form of CAD/CAM program, they still use hand-drawn sketches often during the initial stages of design.

Precision machining for a variety of materials, including steel, bronze, graphite, glass and plastic. Various precision machining tools will be used depending on the size of the project and the materials used. Any combination of lathes, milling machines, drill presses, saws and grinders, and high speed robots can be used. The aerospace industry may use high speed machining, while the woodworking tool manufacturing industry may use photochemical etching and milling processes. Production runs or a specific number of any specific item can be in the thousands, or only a few. Precision machining usually requires programming of CNC equipment, which means they are digitally controlled by computers. CNC equipment allows precise dimensions to be followed throughout the operation of the product.
