Parameters Description Unit
(only for
ShopTurn)
Clamp/release spindle (only for end face Y/peripheral surface Y)
The function must be set up by the machine manufacturer.
Z1 Thread length (inc) or end point of the thread (abs) mm
D Maximum depth infeed mm
DF
• Percentage for each additional infeed
DF=100: Infeed increment remains constant
DF<100: Infeed increment 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
%
mm
V1 Minimum infeed - (only for DF, percentage for each additional infeed)
Parameter V1 is only available 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.
mm
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/rev: Predrilling feedrate = 0.1 mm/rev
AZ
(only for G code)
Predrilling depth with reduced drilling feedrate - ("yes", only for predrilling) mm
Through boring
Remaining drilling depth with drilling feedrate
• Yes
• No
ZR Residual drilling depth for through boring - ("yes", only for through boring) mm
FR
Drilling feedrate for remaining drilling depth - ("yes", only for through boring) mm/min
mm/rev
Chip removal
Stock removal before thread milling
• Yes
• No
Return to workpiece surface for stock removal before thread milling.
Thread
Direction of rotation of the thread
• Righthand thread
• Lefthand thread
