Define the two planes, the R plane and the initial plane, that you use to avoid obstructions when using hole-machining canned cycles.
R plane: The Z surface specified by the R word in the canned cycle command. This position is usually right above the work surface.
Initial plane: The last programmed Z position prior to the canned cycle command.

Name the two things all hole-machining canned cycles share in common.
- All hole-machining canned cycles are modal
- All hole-machining canned cycles cause four predetermined activities. They rapid to the hole location in XY, rapid to the R plane, machine the hole and retract from the hole.
