Parameter Description
V1 Minimum infeed - (only for DF, percentage for each additional infeed)
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.
Predrilling Predrilling with reduced feedrate
● Yes
● No
The reduced drilling feedrate is obtained as follows:
Drilling feedrate F1 < 0.15 mm/rev: Predrilling feedrate = 30% of F1
Drilling feedrate F1 ≥ 0.15 mm/U: Predrilling feedrate = 0.1 mm/rev
ZA Predrill to the depth with reduced drilling feedrate (inc) - ("yes", only for predrilling)
Through drilling Remaining drilling depth with drilling feedrate
● Yes
● No
ZD Depth for feedrate reduction - ("yes", only for through drilling)
FD Feedrate for through drilling - ("yes", only for through drilling)
Swarf removal Swarf removal before thread milling
● Yes
● No
Return to workpiece surface for swarf removal before thread milling.
Thread Direction of rotation of the thread
● Right-hand thread
● Left-hand thread
F2 Feedrate for thread milling
Table Thread table selection:
● without
● ISO metric
● Whitworth BSW
● Whitworth BSP
● UNC
Selection - (not for Selection of table value: e.g.
table "Without")
● M3; M10; etc. (ISO metric)
● W3/4"; etc. (Whitworth BSW)
● G3/4"; etc. (Whitworth BSP)
● N1" - 8 UNC; etc. (UNC)
