Parameter Description
Machining posi‐
● Single position
tion (only for G
Drill hole at programmed position
code)
● Position pattern
Position with MCALL
F1 Drilling feedrate
(only for G-code)
Z0 (only for G Reference point Z
code)
Z1 Thread length (inc) or end point of the thread (abs)
D Maximum depth infeed
● D ≥ Z1: Infeed to the final drilling depth
● D < Z1: Several infeeds with stock removal
DF
● Percentage for each additional infeed
DF=100: Infeed increment remains constant
DF<100: Amount of infeed is reduced in direction of final drilling depth Z1
Example: last infeed 4 mm; DF 80%
next infeed = 4 x 80% = 3.2 mm
next but one infeed = 3.2 x 80% = 2.56 mm etc.
● Amount for each additional infeed
