jpf 1. Introduction to CNC Milling

CNC stands for Computer Numerical Control. In CNC machining a computer is used to control the machine tool instead of an operator. This will make it possible for a novice machinist to create complex parts. We will use milling machines to produce our designs. A schematic of a manual milling machine is shown in Figure 1. CNC part programs control CNC machine tools.
