Parameter Description Unit
Machining
position
(only G code)
● Single position
Drill hole at programmed position.
● Position pattern (MCALL)
Position with MCALL
Machining
● Swarf removal
The drill is retracted from the workpiece for swarf removal.
● Chip breaking
The drill is retracted by the retraction distance V2 for chip breaking.
Z0 (only G code) Reference point Z mm
Drilling depth
● Shank (drilling depth in relation to the shank)
The drill is inserted into the workpiece until the drill shank reaches the value
programmed 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 programmed
for Z1.
Z1 Final drilling depth (abs) or final drilling depth in relation to Z0 (inc)
It is inserted into the workpiece until it reaches Z1.
mm
FD1 Percentage for the feedrate at the first infeed. %
D - (only for G
code)
First drilling depth (abs) or first drilling depth in relation to Z0 (inc) mm
D - (only ShopMill) Maximum depth infeed 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 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.
mm
Clearance dis‐
tance
(for swarf removal
only)
● Manual
The clearance distance must be entered manually.
● Automatic
The clearance distance is calculated by the cycle.
