3. The spigot is machined in parallel with the contours from the outside in. The direction is
determined by the machining direction (climb/conventional) (see "Changing program
settings").
4. When the first plane of the spigot has been machined, the tool retracts from the contour in
a quadrant and then infeeds to the next machining depth.
5. The spigot is again approached in a quadrant and machine in parallel with the contours
from outside in.
6. Steps 4 and 5 are repeated until the programmed spigot depth is reached.
7. The tool retracts to the safety clearance at rapid traverse.
