Bolt-hole circle center X (absolute): Coordinate of
the center point of the circle in the X axis
Bolt-hole circle center Y (absolute): Coordinate
of the center point of the circle in the Y axis
Bolt-hole circle diameter: Diameter of the bolt
hole circle
Starting angle: Polar angle of the first machining
position. Reference axis: Reference axis of the
