Explanations
Positioning axis and drilling axis
As shown below, a drilling G code determines the positioning axes as well as the
drilling axis. The C-axis and X or Z-axis correspond to the positioning axes. The
drilling axis is represented by the X or Z-axis: These axes are not used as positio-
ning axes.

G83, G84, G85
G87, G88, G89
G83 and G87, G84 and G88, and G85 and G89 have the same sequence except
for the drilling axis.
Drilling mode
The G codes (G83--G85 / G87--89) are modal, and remain active until they are can-
celed. The current state is the drilling mode whenever they are active. The data is
retained until modified or canceled once drilling data is specified in the drilling
mode.
All necessary drilling data have to be specified at the beginning of the canned cy-
cles. Only data modifications are allowed to be specified while canned cycles are
being carried out.
