Full circle
 Center in 1st axis : Coordinate of the circle center point ( 1 )
in the major axis of the working plane
 Center in 2nd axis : Coordinate of the circle center point ( 2 )
in the minor axis of the working plane
 Diameter : Diameter of the bolt hole circle
 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
 Number of positions : Total number of machining positions
on the circle
 Top surface coordinate : Coordinate of the top surface of
the workpiece
smarT.NC always calculates the angle increment between
two machining positions by dividing 360° by the number of
machining operations.
