Parameter
Description
Z0
Reference point Z (abs)
Drilling depth
Referred to
● Shank
The drill is inserted until the drill shank reaches the value programmed for Z1. The
angle entered in the tool list is taken into account.
● Tip
The drill is inserted until the drill tip reaches the value programmed for Z1.
Z1
Final drilling depth (abs) or final drilling depth in relation to Z0 (inc)
D
Maximum depth infeed
FD1
Percentage for the feedrate for the first infeed
DF
● Percentage for each additional infeed or
● Amount for each additional infeed
DF = 100: Infeed increment remains constant
DF < 100: Infeed increment is reduced in direction of final drilling depth.
Example: DF = 80
Last infeed was 4 mm;
4 x 80% = 3.2; next infeed increment is 3.2 mm
3.2 x 80% = 2.56; next infeed increment is 2.56 mm, etc.
V1
Minimum depth infeed
Parameter V1 is available only if DF<100% has been programmed.
A minimum infeed is programmed using parameter V1.
V2
Retraction distance after each machining step – (only for "chipbreaking" operation)
Clearance dis‐
- (only for "swarf removal" operation)
tance
● Manual
● Automatic
V3
Clearance distance – (for "manual" clearance distance only)
DT
● Dwell time in seconds
● Dwell time in revolutions
XD
Center offset in X direction
The center offset can be used for example to produce a drill hole with an exact fit. A rotary
drill (rotary drill type) or U drill (drill type) is required. Other drill types are not suitable.
The maximum center offset is stored in a machine data code.
