Circle segment
U Center in 1st axis : Coordinate of the circle center point ( 1 )
in the major axis of the working plane
U Center in 2nd axis : Coordinate of the circle center point ( 2 )
in the minor axis of the working plane
U Diameter : Circle diameter
U Starting angle : Polar angle of the first machining position.
Reference axis: Major axis of the active machining plane
(e.g. X for tool axis Z). You can enter a positive or negative
value.
U Stepping angle : Incremental polar angle between two
machining positions. You can enter a positive or negative
value. Changing the stepping angle automatically changes
the defined stopping angle.
U Number of positions : Total number of machining positions
on the circle
U Stopping angle : Polar angle of the last bore hole. Reference
axis: Major axis of the active machining plane (e.g. X for tool
axis Z). You can enter a positive or negative value. Changing
the stopping angle automatically changes the stepping
angle if one was defined.
