6.32.5. (G81,G82,G84,G85,G86,G89) canned cycle definition
The basic structure of the block in which one of these canned cycles is defined, is as follows:
N4 G8? G(98 or 99) (V+/-4.3) (W+/-4.3) X+/-4.3 Y+/-4.3 Z+/-4.3 I+/-4.3 K2.2 N2
N4 :Block number (0-9999).
G8? :Code of the canned cycle selected.
G98 : Withdrawal of the axis perpendicular to the main plane to the starting plane, after
completing the machining of the hole.
G99 : Withdrawal of the axis perpendicular to the main plane up to the reference plane
(approach), after completing the machining of the hole. Reference plane identifies
a plane that is close to the part’s surface.
X+/-4.3 :Their values have different meaning depending on the plane in which we are
Y+6-4.3 :operating.
Z+/-4.3 :

* If the 4th W axis or the 5th V axis is perpendicular to the main plane, it must be a linear axis.
But if it is one of the axis of the main plane, it may also be a rotary axis.
MAIN
PLANE VALUE
MEANING
They define the movement of the axes of the main plane necessary to
position the tool in the center of the first machining. The values will be
either absolute or incremental depending on the function on which we
are operating (G90 or G91).
The movements will be carried out either in rapid or in F operation
feedrate, depending on the function on which we are operating (G00 or
G01).
That point can be also programmed in polar coordinates.
It identifies the movement of the axis perpendicular to the main plane,
from the starting plane up to the reference plane (approach). This
movement will be executed in rapid (G00). The values will be either
absolute or incremental, depending on the function on which we are
operating (G90 or G91). This value must necessarily be programmed.
