Parameter Description
Machining
Single position
•
position
Drill hole at programmed position.
(only for G
Position pattern
•
code)
Position with MCALL
Z0 (only for G Reference point Z
code)
Machining
Stock removal
•
The drill is retracted from the workpiece for stock removal.
Chipbreaking
•
The drill is retracted by the retraction distance V2 for chipbreaking.
Drilling depth
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.
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)
code)
D - (only for Maximum depth infeed
ShopMill)
FD1 Percentage for the feedrate for the first infeed
DF 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.
