Format
N... G98(G99) G82 X... Y... Z... (R...) P... F... K...
The tool traverses down to end depth with feed
speed, dwells turning to clean the hole ground and
retracts with rapid feed.
Dwell P

Withdrawal
plane R
Applications
Short borings, material with good cutting property
G98(G99) .. Return to starting plane (withdrawal plane)
X, Y ........... Hole position
Z ................ Absolute (incremental) drilling depth
R [mm] ...... Absolute (with G91 incremental) value
of the withdrawal plane
P [msec] .... Dwell at the hole bottom
P1000 = 1 sec
F ................ Feed rate
K ................ Number of repetitions
Dwell P

The tool dips into the work piece for the infeed Q,
drives back to the start plane (G98) or to the withdrawal
plane (G99), to break the chips and remove it
from the hole, traverses with rapid speed until 1 mm
over the previous drilling depth, dips in again for the
infeed Q etc. until end depth is reached and retracts
with rapid feed.
Applications
deep borings, (soft) material with long chips
