Machining
• Chipbreaking
• Swarf removal
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)

V3
Clearance distance – (for "manual" clearance distance only)
DT
• Dwell time in seconds
