It is typically completed on a lathe using a tool called a boring bar, which is a cylindrical tool with a cutting insert. Because boring machining is often performed on a lathe, it is commonly, but incorrectly, referred to as "internal turning." While the process is often performed on a lathe, it can also be performed on CNC milling machines.

Slot milling, also called groove milling, is a machining process where a rotating cutting tool is used to cut a slot in the workpiece. The slot can be any shape or size, the possibilities are endless. The slot milling cutter and machine, however, should be capable of forming the slot shape in the solid workpiece.

So, CNC machining is any kind of machining process controlled by a computer. Computerized automation allows parts to be made more quickly, accurately, precisely, and with more complex geometries than those produced via manual machining. CNC also reduces manual machining labor that would otherwise be done by humans.
