The tool number (or T code) can come from hree places: the pocket, the tool, and the operation. The tool number is inherited from the pocket level to the tool level to the operation level. Based on what the T code means on your NC machine, you need to decide which is the best way for you to assign tool numbers in your programs. </p>
