Circular arc
8 Center in 1st axis: Coordinate of the circle center point
( 1 ) in the major axis of the working plane.
8 Center in 2nd axis: Coordinate of the circle center point
( 2 ) in the minor axis of the working plane.
8 Diameter: Circle diameter.
8 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.
8 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.
8 Number of repetitions: Total number of machining
positions on the circle.
8 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.
