Parameter
Description
Drilling depth
Shank (drilling depth in relation to the shank)
•
The drill is inserted into the workpiece until the drill shank reaches the value pro-
grammed for Z1. The angle entered in the tool list is taken into account.
Tip (drilling depth in relation to the tip)
•
The drill is inserted into the workpiece until the drill tip reaches the value pro-
grammed for Z1.
Note: If it is not possible to define an angle for the drill in the tool management, it will
not be possible to select tip or shank (always tip, 0 field).
Z1
Drilling depth (abs) or drilling depth in relation to Z0 (inc).
It is inserted into the workpiece until it reaches Z1.
D
First drilling depth (abs) or first drilling depth in relation to Z0 (inc).
(only for G code)
D (only for Shop-
Maximum depth infeed.
Turn)
FD1
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.
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.
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.
V2
Retraction distance after each machining step – (for chip breaking only).
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.
Clearance dis-

tance (for swarf
The clearance distance must be entered manually.
removal only)
Automatic
•
The clearance distance is calculated by the cycle.
V3
Clearance 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.
