Parameter Description
PL (only for G Machining plane
code)
SC (only for G Safety clearance
code)
Drilling depth Drilling depth referred to the shaft or tip

D 1. Drilling depth referred to Z0 (inc.)
FD1 Percentage for the feedrate for the first infeed
DF Percentage for the feedrate for each additional infeed
Infeed increment is continually reduced in the direction of
final drilling depth
V1 Minimum infeed
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
Clearance distance The clearance distance is calculated by the cycle.
DTB Dwell time at each drilling depth
N - (only for Number of chipbreaking strokes before each swarf removal
"chipbreaking and operation
swarf removal")
Retraction for swarf Swarf removal at the pilot hole depth or safety clearance
removal
DTS Dwell time for swarf removal in seconds
