CNC Z32 - Programming Guide (LATHES)
G881: Normal drilling
Z (or X)
: hole end position
J
: approaching position. It is the machining starting
position
E:
final return position.
NT:
dwell time at hole end
F:
Feed
Notes:
In case of holes drilled in X direction, the values X,
J, E are considered as diametric or radial, depending
on the active mode when the drilling is programmed.

G882: Deep drilling with chip breakage
Z (or X):
hole end position
J:
approaching position. It is the machining starting
position
E:
final return position.
NT:
dwell time at hole end
K
: depth increment before chip breakage
I:
retraction for chip breakage. If a null value is
programmed, or if the I parameter is not programmed, a
default value of 0.2 is assumed.

Note:
In case of holes drilled in X direction, the values X, J, E, K and I are considered as diametric or
radial, depending on the active mode when the drilling is programmed.
