Code numbers with traversing direction for LFTXT
Starting from the reference plane, you will find the code numbers with traversing directions in
the following diagram.
The retraction in the tool direction is defined for
The "fast retraction" function is deactivated with
Risk of collision
When the tool radius compensation is activated, then:
 For
 For
should not be used, as in these cases, the tool would move to the contour and would
collide with the workpiece.

the direction in the working plane is derived from the following assignment:
LFWP
: X/Y plane
G17
: Retraction in the X direction
ALF=1
: Retraction in the Y direction
ALF=3
: Z/X plane
G18
: Retraction in the Z direction
ALF=1
: Retraction in the X direction
ALF=3
: Y/Z plane
G19
: Retraction in the Y direction
ALF=1
: Retraction in the Z direction
ALF=3
