Circular pattern with circular slots

For circular slots in circular patterns you program the pattern
positions, the center of curvature, the curvature radius and the
position of the slots.
The control positions the slots as follows:
Slots are arranged at the distance of the
the pattern center
Pattern center = center of curvature
Pattern radius = curvature radius
Slots are arranged at the distance of the
curvature radius
Pattern center <> center of curvature
Pattern radius <> curvature radius
In addition, the position
Normal position:
The starting angle of the slot applies as a
the pattern position
The starting angle is added to the pattern position
Original position:
The starting angle of the slot applies as an
The following examples show the programming of a circular pattern
with circular slots.
Slot centerline as reference and normal position
Programming:
Pattern center = center of curvature
Pattern radius = curvature radius
Normal position
These commands arrange the slots at the distance of the
radius about the pattern center.
