Programming technological functions (cycles)
Drill hole at programmed position.
(only for G
Position with MCALL
Z0 (only for G
Reference point Z
The drill is retracted from the workpiece for stock removal.
The drill is retracted by the retraction distance V2 for chipbreaking.
Shank (drilling depth in relation to the shank)
The drill is inserted into the workpiece until the drill shank reaches the value
programmed for Z1. The angle entered in the tool list is taken into account.
Tip (drilling depth in relation to the tip)
The drill is inserted into the workpiece until the drill tip reaches the value
programmed for Z1.
Drilling depth (abs) or drilling depth in relation to Z0 (inc)
It is inserted into the workpiece until it reaches Z1.
D - (only for G
1. Drilling depth (abs) or 1st drilling depth in relation to Z0 (inc)
D - (only for
Maximum depth infeed
Percentage for the feedrate for the first infeed
Amount for each additional infeed
Percentage for each additional infeed
DF = 100%: Infeed increment remains constant
DF < 100%: Infeed increment is reduced in direction of final drilling depth.
Example: Last infeed was 4 mm; DF is 80%
next infeed = 4 x 80% = 3.2 mm
next infeed = 3.2 x 80% = 2.56 mm etc.
Minimum infeed - (only for DF in %)
Parameter V1 is provided only if DF< 100 has been programmed.
If the infeed increment becomes minimal, a minimum infeed can be programmed in
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.
Retraction distance after each machining step – (for chipbreaking only)
Distance by which the drill is retracted for chipbreaking.
V2 = 0: The tool is not retracted but is left in place for one revolution.
Clearance distance – (for stock removal only and manual clearance distance)
Distance to the last infeed depth that the drill approaches in rapid traverse after stock
