Retraction
Planar retraction mode:
• Quadrant:
Part of a spiral (only with path milling left and right of the contour)
• Semi-circle:
Part of a spiral (only with path milling left and right of the contour)
• Straight line:
Retraction strategy
• axis-by-axis
• spatial
R2
Retraction radius - (only for "quadrant or semi-circle" retraction)
mm
L2
Retraction distance - (only for "straight line" retraction)

Lift mode
If more than one depth infeed is necessary, specify the retraction height to
which the tool retracts between the individual infeeds (at the transition from the
end of the contour to the start).
Lift mode before new infeed
• No retraction
• to RP
• Z0 + safety clearance
• By the safety clearance
FS
Chamfer width for chamfering - (only for chamfering machining)
mm
ZFS
Insertion depth of tool tip (abs or inc) - (for chamfering machining only)
mm
* Unit of feedrate as programmed before the cycle call
