Description
Unit
Machining
● One cut
● Chip breaking
● Swarf removal
● Chip breaking and swarf removal
FD1
Percentage for the feedrate for the first infeed
%
D
First drilling depth (abs) or first drilling depth in relation to Z0 (inc)
mm
DF
Infeed:
● Degression amount by which each additional infeed is reduced (inc)
● 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 depth infeed - (only for DF in %)
Parameter V1 is only provided 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
(for chip break‐
ing only)
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
DTB
● Dwell time at drilling depth in seconds
● Dwell time at drilling depth in revolutions
s
rev
Clearance dis‐
tance - (for
stock removal
only)
● 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 chip removal
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
