CNC Milling. With a manual milling machine usually, you will have the Zaxis locked and the workpiece is moved in the X and Yaxis. This created a 2D profile on your work. When you want complex 3D profiles machined on the surface of the workpiece you may need to move all the 3 axes simultaneously. The CNC milling machines makes this process easy.

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.
