Parameter Description Unit
DF
Infeed:
• Amount for each additional infeed
• 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 Retraction distance after each machining step – (for chipbreaking only)
Distance by which the drill is retracted for chipbreaking.
V2 = 0: The tool is not retracted but is left in place for one revolution.
mm
Limit distance (for
swarf removal
only)
• Manual
The limit distance must be entered manually.
• Automatic
The limit distance is calculated by the cycle.
V3 Limit distance – (for swarf removal only and manual limit distance)
Distance to the last infeed depth that the drill approaches in rapid traverse after swarf
removal.
