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 can perform inside the diameter, turning (also known as boring) to produce tubular like components to various geometries. A machine tool that performs turning is called a lathe.
