By this format, the CNC program is made up of blocks. Each block is made up of CNC words. Each CNC word has a letter address and a numerical value. For example, X10 is a word means the tool moves to a position ten mm from the program zero point in X axis (if working in the absolute mode). One very good analogy to what happens in a CNC program is found in any set of step by step instructions1. Then, in step by step order, the programmer will give a set of commands that makes the machine behave accordingly. An experienced programmer should be able to visualize the movements the
