Important: Figure 24.9 does not show the optional final pass being made.

This is for drawing clarity.

In Figure 24.9, after the roughing passes of one pocket have been

completed, the control does not perform a normal retract move out of the

pocket. Instead the control follows the contour out of the pocket and then

proceeds on to the next pocket or finishes the routine.
