Description
Machining plane:

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.
Feedrate
Depth infeed rate
∇ (roughing)
•
∇∇∇ (finishing)
•
• ∇ + ∇∇∇ (roughing and finishing)
∇∇∇ edge (edge finishing)
•
Chamfering
•
Full circle
•
The circumferential grooves are positioned around a full circle. The groove
spacing is uniform and is calculated by the controller.
Pitch circle
•
The circumferential grooves are positioned around a pitch circle. The groove
spacing can be determined on the basis of angle α2.
The positions refer to the center point:
Reference point X
Reference point Y
Reference point Z
Number of grooves
Radius of circumferential groove
Starting angle
Opening angle of the groove
Advance angle - (for pitch circle only)
Groove width
Groove depth (abs) or depth relative to Z0 (inc) – (only for ∇, ∇∇∇, ∇ + ∇∇∇ and
∇∇∇ edge)
Maximum depth infeed - (only for ∇, ∇∇∇, ∇ + ∇∇∇ and ∇∇∇ edge)
Chamfer width for chamfering (inc) - (for chamfering only),
Insertion depth of tool tip (abs or inc) - (for chamfering only),
