Z0 Reference point Z
Z1 Final drilling depth X (abs) or final drilling depth in relation to Z0 (inc)
D Maximum depth infeed
XD Center offset in X direction
The center offset can be used for example to produce a drill hole with an exact fit. A rotary
drill (rotary drill type) or U drill (drill type) is required. Other drill types are not suitable.
The maximum center offset is stored in a machine data code.
