Parameter Description Unit
DF Infeed:
● Degression amount by which each additional infeed is reduced.
● Percentage for each additional infeed.
DF = 100%: Infeed increment remains constant.
DF < 100%: Infeed increment is reduced in direction of final drilling depth.
Example: Last infeed was 4 mm; DF is 80%
Next infeed = 4 x 80% = 3.2 mm
Next infeed = 3.2 x 80% = 2.56 mm, etc.
mm
%
V1 Minimum infeed - (only for DF in %)
Parameter V1 is only available if DF<100 has been programmed.
If the infeed increment becomes very small, a minimum infeed can be programmed
in parameter "V1".
V1 < Infeed increment: The tool is inserted by the infeed increment.
V1 > Infeed increment: The tool is inserted by the infeed value programmed under
V1.
mm
V2
(only for chip
breaking and
soft first cut "no")
Retraction distance after each machining step.
Distance by which the drill is retracted for chip breaking.
V2 = 0: The tool is not retracted but is left in place for one revolution. mm

● Dwell time at drilling depth in seconds
● Dwell time at drilling depth in revolutions

Clearance dis‐
tance
(only for swarf re‐
moval and soft
first cut "no")
● Manual
The clearance distance must be entered manually.
● Automatic
The clearance distance is calculated by the cycle.
V3 – (for "man‐
ual" clearance
distance only)
Clearance distance (inc) mm
N - (only for
"chip breaking
and swarf re‐
moval")
Number of chip breaking strokes before each swarf removal operation.
Retraction for
swarf removal
● Swarf removal at the pilot hole depth
● Swarf removal at the safety clearance
DTS
● Dwell time for swarf removal in seconds
● Dwell time for swarf removal in revolutions
s
rev
Through drilling
● Yes
Through drilling with feedrate FD
● No
Drilling with constant feedrate
ZD - (only for
through drilling
"yes")
Depth for through drilling feedrate (abs) or depth for through drilling feedrate in
relation to Z1 (inc)
