CNC Milling is an automated process used to manufacture 2D and 3D parts by removing material from raw stock.

To make a CNC milled part, a block or sheet is placed on a table below a spindle which holds a cutting tool. A computer controls the tool used, the rotation speed and the vertical motion of the spindle, and the horizontal motion of the table. This allows loaded cutters such as drills, taps and end mills to remove portions of the material to create shapes.

CNC turning is a process by which material is cut to create round shapes, typically using a CNC Lathe.

The workpiece is placed inside the lathe and rotates while a cutter removes material until only the desired shape remains. Turning is ideal for cylindrical parts and is primarily done using round rod material, but square and hexagonal bar stock can also be used.
