5-174 SINUMERIK 840D sl Operation/Programming ShopTurn (BAT) – 08/2005 Edition
Parameters Description Unit
T, D, F, S, V See Sec. "Creating program blocks".
Position Select from 8 different positions:
End face/End face C – Front
End face/End face C – Rear
Peripheral surface/Peripheral surface C – Inner
Peripheral surface/Peripheral surface C – Outer
End face Y – Front (only when Y axis exists)
End face Y – Rear (only when Y axis exists)
Peripheral surface Y – inner (only when Y axis exists)
Peripheral surface Y – Rear (only when Y axis exists)
Clamp/release spindle
The function must be set up by the machine manufacturer.
Stock removal
Chipbreaking
The drill is retracted from the workpiece for stock removal.
The drill is retracted by the retraction amount V2 for chipbreaking.
Shank
Tip
The drill is inserted into the workpiece until the drill shank reaches the programmed
depth 1.
The insertion angle entered in the tool list is applied.
The drill is inserted into the workpiece until the drill tip reaches the programmed
depth 1.
Z1 Insertion depth for drill tip or drill shank with reference to Z0.
(abs. or inc.) – (only for end face/end face C and end face Y)
mm
X1 Insertion depth for drill tip or drill shank with reference to X0.
(abs. or inc.) – (only for peripheral surface/peripheral surface C and peripheral
surface Y)
mm
D Maximum infeed mm
DF Percentage for each additional infeed
DF = 100: Amount of infeed remains constant
DF < 100: Amount of infeed 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 infeed
Parameter V1 is available only if DF<100% has been programmed.
If the amount of infeed is very small a minimum infeed can be programmed with
parameter V1.
V1 < Amount of infeed: Infeed with infeed value.
V1 < Amount of infeed: Infeed with the value programmed in V1.
mm
V2 Retraction amount (for chipbreaking only)
Amount by which the drill is retracted for chipbreaking.
V2=0: The tool is not retracted but is left in place for one revolution.
mm
V3 Limit distance (for stock removal only)
Distance to last infeed depth that the drill approaches at rapid traverse after stock
removal.
Automatic: The clearance distance is calculated by ShopTurn.
mm
DT Dwell time for release cut s
