Programming technological functions (cycles)
10.2 Milling
Parameter Description
ZFS Insertion depth of tool tip (abs or inc) - (for chamfering only),
UXY Plane finishing allowance - (only for ∇, ∇∇∇ and ∇∇∇ edge)
Positioning Positioning motion between the slots:
● Straight line:
Next position is approached linearly in rapid traverse.
● Circular:
Next position is approached along a circular path at the feedrate defined in the
machine data.
* Unit of feedrate as programmed before the cycle call

Machining The following machining operations can be selected:
● ∇ (roughing)
● ∇∇∇ (finishing)
● ∇∇∇ edge (edge finishing)
● Chamfering
Circular pattern
● Full circle
● Pitch circle

The circumferential slots are positioned around a full circle. The distance from one
circumferential slot to the next circumferential slot is always the same and is
calculated by the control.
The circumferential slots are positioned around a pitch circle. The distance from one
circumferential slot to the next circumferential slot can be defined using angle α2.
