CAUTION
D In each canned cycle,
R_ (distance between the initial level and point R) is always
handled as a radius.
Z_ or X_ (distance between point R and the bottom of the
hole) is, however, handled either as a diameter or radius,
depending on the specification.
D For the B or C G–code system, G90 or G91 can be used to
select an incremental or absolute command for hole
position data (X, C or Z, C), the distance from point R to the
bottom of the hole (Z or X), and the distance from the initial
level to the point R level (R).
