Retraction plane (abs)
Normally, reference point Z0 and retraction plane RP have different values. The
cycle assumes that the retraction plane is in front of the reference point.
Safety clearance (inc)
Acts in relation to the reference point. The direction in which the safety clearance
is active is automatically determined by the cycle.

The positions refer to the reference point:
Reference point X – (for single position only)
Reference point Y – (for single position only)
Reference point Z
Groove width
Groove length
Angle of rotation
Groove depth (abs) or depth relative to Z0 (inc) – (only for ∇, ∇∇ and ∇∇∇ edge)
Maximum depth infeed - (only for ∇, ∇∇ or ∇∇∇ edge)
Chamfer width for chamfering (inc) - (for chamfering only),
Insertion depth of tool tip (abs or inc) - (for chamfering only)
Plane finishing allowance - (not for chamfering)
Depth finishing allowance (groove base) - (not for chamfering or edge finishing)
