Percentage for the feedrate at the first infeed.
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.
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.

%
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
mm
V2
(only for chip
breaking and
soft first cut
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.

• Manual
The clearance distance must be entered manually.
• Automatic
The clearance distance is calculated by the cycle.

Number of chip breaking strokes before each swarf removal operation.
