Turning, CNC turning, or manual turning is the process used to produce cylindrical components in a lathe. A CNC Turning Center The abbreviation CNC stands for Computer(ized) Numerical(ly) Control(led), and refers specifically to the computer control of machine tools for the purpose of (repeatedly) manufacturing complex parts in metal as well as other materials, using a program written in a notation conforming to the... Conventional metalworking lathe In woodturning, metalworking, metal spinning, and glassworking, a lathe is a machine tool which spins a block of material so that when abrasive, cutting, or deformation tools are applied to the block, it can be shaped to produce an object which has rotational symmetry about an axis...


A cylindrical piece of stock is rotated and a cutting tool is traversed along 2 axes of motion to produce precise diameters and depths. Turning can be either on the outside of the cylinder or on the inside (also known as boring) to produce tubular components to various geometries. See stock (disambiguation) for other meanings of the term stock In financial terminology, stock is the capital raised by a corporation, through the issuance and sale of shares. ...

Facing is a related term. It involves moving the cutting tool across the face (or end) of the workpiece and is performed by the operation of the topslide, as distinct from the longitudinal feed (turning). It is commonly associated with the use of a lathe although it may be used in relation to vertical boring mills or similar operations. Conventional metalworking lathe In woodturning, metalworking, metal spinning, and glassworking, a lathe is a machine tool which spins a block of material so that when abrasive, cutting, or deformation tools are applied to the block, it can be shaped to produce an object which has rotational symmetry about an axis...
